1. Introduction to the CompactFlash Memory Card
The SanDisk CompactFlash(R) Memory Card (CF) products provide high capacity solid-state flash memory that electrically complies with the Personal Computer Memory Card International Association ATA (PC Card ATA) standard. (In Japan, the applicable standards group is JEIDA.) The CompactFlash Memory Card Series also supports a True IDE Mode that is electrically compatible with an IDE disk drive. The original CF form factor card can be used in any system that has a CF slot, and with a Type II PCMCIA adapter can be used in any system that has a PCMCIA Type II or Type III socket. The CompactFlash Memory Cards use SanDisk Flash memory, which was designed by SanDisk specifically for use in mass storage applications. In addition to the mass storage specific Flash memory chips, the CompactFlash Memory Cards include an on-card intelligent controller that provides a high level interface to the host computer. This interface allows a host computer to issue commands to the memory card to read or write blocks of memory. The host addresses the card in 512 byte sectors. Each sector is protected by a powerful Error Correcting Code (ECC). The CompactFlash Memory Card on-card intelligent controller manages interface protocols, data storage and retrieval as well as ECC, defect handling and diagnostics, power management and clock control. Once the CompactFlash Memory Card has been configured by the host, it appears to the host as a standard ATA (IDE) disk drive. Additional ATA commands have been provided to enhance system performance. The host system can support as many cards as there are CompactFlash and PCMCIA Type II or III card slots. The original form factor CompactFlash Memory Cards require a PCMCIA Type II Adapter to be used in a PCMCIA Type II or Type III socket. Figure 1-1 shows a block diagram of the CompactFlash Memory Card.

1.6. Functional Description
CompactFlash Memory Cards contain a high level, intelligent subsystem as shown in the block diagram, Figure 1-1. This intelligent (microprocessor) subsystem provides many capabilities not found in other types of memory cards. These capabilities include the following:
* * * * *
Standard ATA register and command set (same as found on most magnetic disk drives). Host independence from details of erasing and programming flash memory. Sophisticated system for managing defects (analogous to systems found in magnetic disk drives). Sophisticated system for error recovery including a powerful error correction code (ECC). Power management for low power operation.

Introduction to the CompactFlash Memory Card
1.6.1. Technology Independence The 512-byte sector size of the CompactFlash Memory Card is the same as that in an IDE magnetic disk drive. To write or read a sector (or multiple sectors), the host computer software simply issues a Read or Write command to the CompactFlash Memory Card. This command contains the address and the number of sectors to write/read. The host software then waits for the command to complete. The host software does not get involved in the details of how the flash memory is erased, programmed or read. This is extremely important as flash devices are expected to get more and more complex in the future. Since the CompactFlash Memory Card Series uses an intelligent on-board controller, the host system software will not require changing as new flash memory evolves. In other words, systems that support the CompactFlash Memory Card today will be able to access future SanDisk cards built with new flash technology without having to update or change host software. 1.6.2. Defect and Error Management CompactFlash Memory Cards contain a sophisticated defect and error management system. This system is analogous to the systems found in magnetic disk drives and in many cases offers enhancements. If necessary, CompactFlash Memory Cards will rewrite data from a defective sector to a good sector. This is completely transparent to the host and does not consume any user data space. The CompactFlash Memory Card soft error rate specification is much better than the magnetic disk drive specification. In the extremely rare case a read error does occur, CompactFlash Memory Cards have innovative algorithms to recover the data. These defect and error management systems, coupled with the solid state construction, give CompactFlash Memory Cards unparalleled reliability. 1.6.3. Wear Leveling Wear Leveling is an intrinsic part of the Erase Pooling functionality of SanDisk CF using NAND memory. The CF WEAR LEVEL command is supported as a NOP operation to maintain backward compatibility with existing software utilities. 1.6.4. Using the Erase Sector and Write without Erase Commands CompactFlash Memory Cards support the CF ERASE SECTOR and WRITE WITHOUT ERASE commands. In some applications, write operations may be faster if the addresses being written are first erased with the ERASE SECTOR command. WRITE WITHOUT ERASE behaves as a normal write command and no performance gain results from its use.

Introduction to the CompactFlash Memory Card
1.6.5. Automatic Sleep Mode A unique feature of the SanDisk CompactFlash Memory Card (and other SanDisk products) is automatic entrance and exit from sleep mode. Upon completion of a command, the CompactFlash Card will enter sleep mode to conserve power if no further commands are received within 5 msec. The host does not have to take any action for this to occur. In most systems, the CompactFlash Memory Card is in sleep mode except when the host is accessing it, thus conserving power. Note that the delay from command completion to entering sleep mode can be adjusted. When the host is ready to access the CompactFlash Memory Card and it is in sleep mode, any command issued to the CompactFlash Card will cause it to exit sleep and respond. The host does not have to follow the ATA protocol of issuing a reset first. It may do this if desired, but it is not needed. By not issuing the reset, performance is improved through the reduction of overhead but this must be done only for the SanDisk products as other ATA products may not support this feature. 1.6.6. Dynamic Adjustment of Performance versus Power Consumption This feature is no longer supported. This command will be treated as a NOP (No Operation) to guarantee backward compatibility. 1.6.7. Power Supply Requirements This is a dual voltage product, which means it will operate at a voltage range of 3.30 volts 5% or 5.00 volts 10%. Per the PCMCIA specification Section 2.1.1, the host system must apply 0 volts in order to change a voltage range. This same procedure of providing 0 volts to the card is required if the host system applies an input voltage outside the desired voltage by more than 15%. This means less than 4.25 volts for the 5.00-volt range and less than 2.75 volts for the 3.30 volt range.

NOTE: 1. These signals are required only for 16-bit access and not required when installed in 8-bit systems. For lowest power dissipation, leave these signals open. 2. Should be grounded by the host. 3. Should be tied to VCC by the host. 4. Please refer to Section 3.3 for definitions of In, Out type. 5. The -CSEL signal is ignored by the card in PC Card modes. However, because it is not pulled up in the card in these modes, it should not be left floating by the host in PC Card modes. In these modes, the pin should be connected by the host to PC Card A25 or grounded by the host. 6. If DMA operations are not used, the signal should be held high or tied to VCC by the host. For proper operation in older hosts: while DMA operations are not active, the card shall ignore this signal, including a floating condition.

CompactFlash Memory Card Interface Description
3.2. Electrical Description
The CompactFlash Memory Card Series is optimized for operation with hosts, which support the PCMCIA I/O interface standard conforming to the PC Card ATA specification. However, the CompactFlash Card may also be configured to operate in systems that support only the memory interface standard. The configuration of the CompactFlash Card will be controlled using the standard PCMCIA configuration registers starting at address 200h in the Attribute Memory space of the CompactFlash Memory Card. Table 3-2 describes the I/O signals. Signals whose source is the host are designated as inputs while signals that the CompactFlash Memory Card sources are outputs. The CompactFlash Card logic levels conform to those specified in the PCMCIA Release 2.1 Specification. See Section 3.3 for definitions of Input and Output type. Table 3-2. Signal Description

This signal is asserted high as the BVD1 signal since a battery is not used with this product. This signal is asserted low to alert the host to changes in the RDY/-BSY and Write Protect states, while the I/O interface is configured. Its use is controlled by the Card Config and Status Register. In the True IDE Mode, this input/output is the Pass Diagnostic signal in the Master/Slave handshake protocol. This output line is always driven to a high state in Memory Mode since a battery is not required for this product. This output line is always driven to a high state in I/O Mode since this product does not support the audio function. In the True IDE Mode, this input/output is the Disk Active/Slave Present signal in the Master/Slave handshake protocol. These Card Detect pins are connected to ground on the CompactFlash Card. They are used by the host to determine if the card is fully inserted into its socket. This signal is the same for all modes. This signal is the same for all modes.

Description These input signals are used both to select the card and to indicate to the card whether a byte or a word operation is being performed. -CE2 always accesses the odd byte of the word. -CE1 accesses the even byte or the Odd byte of the word depending on A0 and -CE2. A multiplexing scheme based on A0, -CE1, -CE2 allows 8 bit hosts to access all data on D0-D7. See Tables 3-11, 3-12, 3-15, and 3-16. This signal is the same as the PC Card Memory Mode signal.

In the True IDE Mode -CS0 is the chip select for the task file registers while -CS1 is used to select the Alternate Status Register and the Device Control Register. This signal is not used for this mode. This signal is not used for this mode. This internally pulled up signal is used to configure this device as a Master or a Slave when configured in the True IDE Mode. When this pin is grounded, this device is configured as a Master. When the pin is open, this device is configured as a Slave. These lines carry the Data, Commands and Status information between the host and the controller. D00 is the LSB of the Even Byte of the Word. D08 is the LSB of the Odd Byte of the Word. These signals are the same as the PC Card Memory Mode signal. In True IDE Mode all Task File operations occur in byte mode on the low order bus D00-D07 while all data transfers are 16 bits using D00-D15. -1, 50 Ground. This signal is the same for all modes. This signal is the same for all modes. O 43 This signal is not used in this mode. The Input Acknowledge signal is asserted by the CompactFlash Card when the card is selected and responding to an I/O read cycle at the address that is on the address bus. This signal is used by the host to control the enable of any input data buffers between the card and the CPU. This signal is used for DMA data transfers between host and device and is asserted by the device when it is ready to transfer data to or from the host. The direction of data transfer is controlled by DIOR- and DIOW-. This signal is used in a handshake manner with DMACK- (i.e., the device waits until the host asserts DMACK- before negating DMARQ, and reasserting DMARQ if there is more data to transfer). I 34 This signal is not used in this mode. This is an I/O Read strobe generated by the host. This signal gates I/O data onto the bus from the CompactFlash Card when the card is configured to use the I/O interface. In True IDE Mode, this signal has the same function as in PC Card I/O Mode.

Pin 35 This signal is not used in this mode.
Description
The I/O Write strobe pulse is used to clock I/O data on the Card Data bus into the CompactFlash controller registers when the card is configured to use the I/O interface. The clocking will occur on the negative to positive edge of the signal (trailing edge).
-IOWR (True IDE Mode) -OE (PC Card Memory Mode) -OE (PC Card I/O Mode) -ATA SEL (True IDE Mode) RDY/-BSY (PC Card Memory Mode) O 37 I 9
In True IDE Mode, this signal has the same function as in PC Card I/O Mode. This is an Output Enable strobe generated by the host interface. It is used to read data from the CompactFlash Card in Memory Mode and to read the CIS and configuration registers. In PC Card I/O Mode, this signal is used to read the CIS and configuration registers. To enable True IDE Mode this input should be grounded by the host. In Memory Mode this signal is set high when the CompactFlash Card is ready to accept a new data transfer operation and held low when the card is busy. The Host memory card socket must provide a pull-up resistor. At power up and at Reset, the RDY/-BSY signal is held low (busy) until the CompactFlash Card has completed its power up or reset function. No access of any type should be made to the CompactFlash Card during this time. The RDY/-BSY signal is held high (disabled from being busy) whenever the following condition is true: The CompactFlash Card has been powered up with +RESET continuously disconnected or asserted.
-IREQ ( PC Card I/O Mode) INTRQ (True IDE Mode) -REG (PC Card Memory Mode) Attribute Memory Select -REG (PC Card I/O Mode) -DMACK (True IDE Mode) I 44
I/O Operation--After the CompactFlash Card has been configured for I/O operation, this signal is used as -Interrupt Request. This line is strobed low to generate a pulse mode interrupt or held low for a level mode interrupt. In True IDE Mode, this signal is the active high Interrupt Request to the host. This signal is used during Memory Cycles to distinguish between Common Memory and Register (Attribute) Memory accesses. High for Common Memory, Low for Attribute Memory. The signal must also be active (low) during I/O Cycles when the I/O address is on the Bus. This signal is used by the host in response to DMARQ to initiate DMA transfers. NOTE: This signal may be negated by the host to suspend the DMS transfer in process. For Multiword DMA transfers, the device may negate DMARQ with the tL specified time once the DMACK- is asserted and reasserted again at a later time to resume DMA operation. Alternatively, if the device is able to continue the data transfer, the device may leave DMARQ asserted and wait for the host to reassert DMACK-. I 41 When the pin is high, this signal resets the CompactFlash Card. The card is Reset only at power up if this pin is left high or open from power-up. The card is also reset when the Soft Reset bit in the Card Configuration Option Register is set. This signal is the same as the PC Card Memory Mode signal. In the True IDE Mode this input pin is the active low hardware reset from the host. -13, 38 +5 V, +3.3 V power.

3.4. Card Configuration
The CompactFlash Memory Cards are identified by appropriate information in the Card Information Structure (CIS). The following configuration registers are used to coordinate the I/O spaces and the Interrupt level of cards that are located in the system. In addition, these registers provide a method for accessing status information about the CompactFlash Card that may be used to arbitrate between multiple interrupt sources on the same interrupt level or to replace status information that appears on dedicated pins in memory cards that have alternate use in I/O cards.

Soft Reset--Setting this bit to one (1), waiting the minimum reset width time and returning to zero (0) places the CompactFlash Memory Card in the Reset state. Setting this bit to one (1) is equivalent to assertion of the +RESET signal except that the SRESET bit is not cleared. Returning this bit to zero (0) leaves the CompactFlash Memory Card in the same un-configured, Reset state as following power-up and hardware reset. This bit is set to zero (0) by power-up and hardware reset. Using the PCMCIA Soft Reset is considered a hard Reset by the ATA Commands. Contrast with Soft Reset in the Device Control Register. This bit is set to one (1) when Level Mode Interrupt is selected, and zero (0) when Pulse Mode is selected. Set to zero (0) by Reset. Configuration Index. Set to zero (0) by reset.

Indicates that one or both of the Pin Replacement register CRdy, or CWProt bits are set to one (1). When the Changed bit is set, -STSCHG Pin 46 is held low if the SigChg bit is a One (1) and the CompactFlash Memory Card is configured for the I/O interface. This bit is set and reset by the host to enable and disable a state-change "signal" from the Status Register, the Changed bit control pin 46 the Changed Status signal. If no state change signal is desired, this bit should be set to zero (0) and pin 46 (-STSCHG) signal will be held high while the CompactFlash Memory Card is configured for I/O. The host sets this bit to a one (1) if the CompactFlash Memory Card is to be configured in an 8 bit I/O mode. The CompactFlash Card is always configured for both 8- and 16-bit I/O, so this bit is ignored. This bit indicates whether the host requests the CompactFlash Memory Card to be in the power saving or active mode. When the bit is one (1), the CompactFlash Card enters a power down mode. When zero (0), the host is requesting the CompactFlash Card to enter the active mode. The PCMCIA Rdy/-Bsy value becomes BUSY when this bit is changed. Rdy/-Bsy will not become Ready until the power state requested has been entered. The CompactFlash Card automatically powers down when it is idle and powers back up when it receives a command. This bit represents the internal state of the interrupt request. This value is available whether or not I/O interface has been configured. This signal remains true until the condition that caused the interrupt request has been serviced. If interrupts are disabled by the -IEN bit in the Device Control Register, this bit is a zero (0).

CompactFlash Memory Card Interface Description
3.5.1. I/O Function The I/O transfer to or from the CompactFlash Memory Card can be either 8 or 16 bits. When a 16-bit accessible port is addressed, the signal -IOIS16 is asserted by the CompactFlash Card. Otherwise, the -IOIS16 signal is de-asserted. When a 16-bit transfer is attempted, and the -IOIS16 signal is not asserted by the CompactFlash Card, the system must generate a pair of 8-bit references to access the word`s even byte and odd byte. The CompactFlash Card permits both 8 and 16 bit accesses to all of its I/O addresses, so -IOIS16 is asserted for all addresses to which the CompactFlash Card responds. Table 3-23. I/O Function

3.7. True IDE Mode I/O Transfer Function
This section contains valuable information on the True IDE Mode I/O Transfer function. 3.7.1. True IDE Mode I/O Function The CompactFlash Memory Card can be configured in a True IDE Mode of operation. This CompactFlash Card is configured in this mode only when the -OE input signal is grounded by the host when power is applied to the card. In this True IDE Mode, the PCMCIA protocol and configuration are disabled and only I/O operations to the Task File and Data Register are allowed. In this mode, no Memory or Attribute Registers are accessible to the host. CompactFlash Cards permit 8 bit data accesses if the user issues a Set Feature Command to put the device in 8-bit Mode. NOTE: Removing and reinserting the CompactFlash Memory Card while the host computer's power is on will reconfigure the CompactFlash Card to PC Card ATA mode from the original True IDE Mode. To configure the CompactFlash Card in True IDE Mode, the 50-pin socket must be power cycled with the CompactFlash Card inserted and -OE (output enable) grounded by the host. Table 3-25 defines the function of the operations for the True IDE Mode. Table 3-25. IDE Mode I/O Function

4. ATA Drive Register Set Definition and Protocol
The CompactFlash Memory Card can be configured as a high performance I/O device through the following ways:
* * *
Standard PC-AT disk I/O address spaces 1F0h-1F7h, 3F6h-3F7h (primary); 170h-177h, 376h-377h (secondary) with IRQ 14 (or other available IRQ). Any system decoded 16-byte I/O block using any available IRQ. Memory space.
The communication to or from the CompactFlash Memory Card is done using the Task File registers, which provide all the necessary registers for control and status information. The PCMCIA interface connects peripherals to the host using four register mapping methods. Table 4-1 is a detailed description of these methods. Table 4-1. I/O Configurations

ATA Drive Register Set Definition and Protocol
1. Register 0 is accessed with -CE1 low and -CE2 low (and A0 = Do not care) as a word register on the combined Odd Data Bus and Even Data Bus (D15-D0). This register may also be accessed by a pair of byte accesses to the offset 0 with -CE1 low and -CE2 high. Note that the address space of this word register overlaps the address space of the Error and Feature byte-wide registers that lie at offset 1. When accessed twice as byte register with -CE1 low, the first byte to be accessed is the even byte of the word and the second byte accessed is the odd byte of the equivalent word access. 2. A byte access to register 0 with -CE1 high and -CE2 low accesses the error (read) or feature (write) register.
4.2. Contiguous I/O Mapped Addressing
When the system decodes a contiguous block of I/O registers to select the CompactFlash Memory Card, the registers are accessed in the block of I/O space decoded by the system as follows: Table 4-3. Contiguous I/O Decoding

NOTES: 1. Register 0 is accessed with -CE1 low and -CE2 low (and A0 = Do not care) as a word register on the combined Odd Data Bus and Even Data Bus (D15-D0). This register may also be accessed by a pair of byte accesses to the offset 0 with -CE1 low and -CE2 high. Note that the address space of this word register overlaps the address space of the Error and Feature byte-wide registers that lie at offset 1. When accessed twice as byte register with -CE1 low, the first byte to be accessed is the even byte of the word and the second byte accessed is the odd byte of the equivalent word access. A byte access to register 0 with -CE1 high and -CE2 low accesses the error (read) or feature (write) register. 2. Registers at offset 8, 9 and D are non-overlapping duplicates of the registers at offset 0 and 1. Register 8 is equivalent to register 0, while register 9 accesses the odd byte. Therefore, if the registers are byte accessed in the order 9 then 8 the data will be transferred odd byte then even byte. Repeated byte accesses to register 8 or 0 will access consecutive (even than odd) bytes from the data buffer. Repeated word accesses to register 8, 9 or 0 will access consecutive words from the data buffer. Repeated byte accesses to register 9 are not supported. However, repeated alternating byte accesses to registers 8 then 9 will access consecutive (even then odd) bytes from the data buffer. Byte accesses to register 9 access only the odd byte of the data. 3. Address lines that are not indicated are ignored by the CompactFlash Memory Card for accessing all the registers in this table.

Byte accesses to register 9 access only the odd byte of the data. 3. Accesses to even addresses between 400h and 7FFh access register 8. Accesses to odd addresses between 400h and 7FFh access register 9. This 1 KByte memory window to the data register is provided so that hosts can perform memory to memory block moves to the data register when the register lies in memory space. Some hosts, such as the X86 processors, must increment both the source and destination addresses when executing the memory to memory block move instruction. Some PCMCIA socket adapters also have auto incrementing address logic embedded within them. This address window allows these hosts and adapters to function efficiently. Note that this entire window accesses the Data Register FIFO and does not allow random access to the data buffer within the CompactFlash Memory Card.

4.5. ATA Registers
NOTE: In accordance with the PCMCIA specification: each of the registers below which is located at an odd offset address may be accessed at its normal address and also the corresponding even address (normal address -1) using data bus lines (D15-D8) when -CE1 is high and -CE2 is low unless -IOIS16 is high (not asserted) and an I/O cycle is being performed. 4.5.1. Data Register (Address--1F0[170];Offset 0, 8, 9) The Data Register is a 16-bit register, and it is used to transfer data blocks between the CompactFlash Memory Card data buffer and the Host. This register overlaps the Error Register. The table below describes the combinations of data register access and is provided to assist in understanding the overlapped Data Register and Error/Feature Register rather than to attempt to define general PCMCIA word and byte access modes and operations. See the PCMCIA PC Card Standard Release 2.0 for definitions of the Card Accessing Modes for I/O and Memory cycles. NOTE: Because of the overlapped registers, access to the 1F1, 171 or offset 1 are not defined for word (-CE2 = 0 and -CE1 = 0) operations. SanDisk products treat these accesses as accesses to the Word Data Register. The duplicated registers at offsets 8, 9 and Dh have no restrictions on the operations that can be performed by the socket.

4.5.2. Error Register (Address--1F1[171]; Offset 1, 0Dh Read Only) This register contains additional information about the source of an error when an error is indicated in bit 0 of the Status register. The bits are defined as follows:
D7 BBK D6 UNC D5 0 D4 IDNF D3 0 D2 ABRT D1 0 D0 AMNF
This register is also accessed on data bits D15-D8 during a write operation to offset 0 with -CE2 low and -CE1 high.
Bit 7 (BBK) Bit 6 (UNC) Bit 5 Bit 4 (IDNF) Bit 3 Bit 2 (Abort) Bit 1 Bit 0 (AMNF) This bit is set when a Bad Block is detected. This bit is set when an Uncorrectable Error is encountered. This bit is 0. The requested sector ID is in error or cannot be found. This bit is 0. This bit is set if the command has been aborted because of a CompactFlash Memory Card status condition: (Not Ready, Write Fault, etc.) or when an invalid command has been issued. This bit is 0. This bit is set in case of a general error.
4.5.3. Feature Register (Address--1F1[171]; Offset 1, 0Dh Write Only This register provides information regarding features of the CompactFlash Memory Card that the host can utilize. This register is also accessed on data bits D15-D8 during a write operation to Offset 0 with -CE2 low and -CE1 high. 4.5.4. Sector Count Register (Address--1F2[172]; Offset 2) This register contains the number of sectors of data requested to be transferred on a read or write operation between the host and the CompactFlash Memory Card. If the value in this register is zero, a count of 256 sectors is specified. If the command was successful, this register is zero at command completion. If not successfully completed, the register contains the number of sectors that need to be transferred in order to complete the request. 4.5.5. Sector Number (LBA 7-0) Register (Address--1F3[173]; Offset 3) This register contains the starting sector number or bits 7-0 of the Logical Block Address (LBA) for any CompactFlash Memory Card data access for the subsequent command.

4.5.6. Cylinder Low (LBA 15-8) Register (Address--1F4[174]; Offset 4) This register contains the low order 8 bits of the starting cylinder address or bits 15-8 of the Logical Block Address. 4.5.7. Cylinder High (LBA 23-16) Register (Address--1F5[175]; Offset 5) This register contains the high order bits of the starting cylinder address or bits 23-16 of the Logical Block Address. 4.5.8. Drive/Head (LBA 27-24) Register (Address 1F6[176]; Offset 6) The Drive/Head register is used to select the drive and head. It is also used to select LBA addressing instead of cylinder/head/sector addressing. The bits are defined as follows:
D7 1 Bit 7 Bit 6 D6 LBA D5 1 D4 DRV D3 HS3 D2 HS2 D1 HS1 D0 HS0
Bit 5 Bit 4 (DRV) Bit 3 (HS3) Bit 2 (HS2) Bit 1 (HS1) Bit 0 (HS0)
This bit is set to 1. LBA is a flag to select either Cylinder/Head/Sector (CHS) or Logical Block Address Mode (LBA). When LBA=0, Cylinder/Head/Sector mode is selected. When LBA=1, Logical Block Address is selected. In Logical Block Mode, the Logical Block Address is interpreted as follows: LBA07-LBA00: Sector Number Register D7-D0. LBA15-LBA08: Cylinder Low Register D7-D0. LBA23-LBA16: Cylinder High Register D7-D0. LBA27-LBA24: Drive/Head Register bits HS3-HS0. This bit is set to 1. This bit will have the following meaning. DRV is the drive number. When DRV=0, drive (card) 0 is selected When DRV=1, drive (card) 1 is selected. The CompactFlash Card is set to be Card 0 or 1 using the copy field of the PCMCIA Socket & Copy configuration register. When operating in the Cylinder , Head, Sector mode, this is bit 3 of the head number. It is Bit 27 in the Logical Block Address mode. When operating in the Cylinder, Head, Sector mode, this is bit 2 of the head number. It is Bit 26 in the Logical Block Address mode. When operating in the Cylinder, Head, Sector mode, this is bit 1 of the head number. It is Bit 25 in the Logical Block Address mode. When operating in the Cylinder, Head, Sector mode, this is bit 0 of the head number. It is Bit 24 in the Logical Block Address mode.
4.5.9. Status & Alternate Status Registers (Address 1F7[177]&3F6[376]; Offsets 7 & Eh) These registers return the CompactFlash Memory Card status when read by the host. Reading the Status register does clear a pending interrupt while reading the Auxiliary Status register does not. The meaning of the status bits are described as follows:
D7 BUSY D6 RDY D5 DWF D4 DSC D3 DRQ D2 CORR D1 0 D0 ERR

ATA Drive Register Set Definition and Protocol
Bit 7 (BUSY)
Bit 6 (RDY) Bit 5 (DWF) Bit 4 (DSC) Bit 3 (DRQ) Bit 2 (CORR) Bit 1 (IDX) Bit 0 (ERR)
The busy bit is set when the CompactFlash Memory Card has access to the command buffer and registers and the host is locked out from accessing the command register and buffer. No other bits in this register are valid when this bit is set to a 1. RDY indicates whether the device is capable of performing CompactFlash Memory Card operations. This bit is cleared at power up and remains cleared until the CompactFlash Card is ready to accept a command. This bit, if set, indicates a write fault has occurred. This bit is set when the CompactFlash Memory Card is ready. The Data Request is set when the CompactFlash Memory Card requires that information be transferred either to or from the host through the Data register. This bit is set when a Correctable data error has been encountered and the data has been corrected. This condition does not terminate a multi-sector read operation. This bit is always set to 0. This bit is set when the previous command has ended in some type of error. The bits in the Error register contain additional information describing the error.
4.5.10. Device Control Register (Address--3F6[376]; Offset Eh) This register is used to control the CompactFlash Memory Card interrupt request and to issue an ATA soft reset to the card. The bits are defined as follows:
D7 X Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 (SW Rst) D6 X D5 X D4 X D3 1 D2 SW Rst D1 -IEn D0 0
Bit 1 (-IEn) Bit 0
This bit is an X (Do not care). This bit is an X (Do not care). This bit is an X (Do not care). This bit is an X (Do not care). This bit is ignored by the CompactFlash Memory Card. This bit is set to 1 in order to force the CompactFlash Memory Card to perform an AT Disk controller Soft Reset operation. This does not change the PCMCIA Card Configuration Registers (4.3.2 to 4.3.5) as a hardware Reset does. The Card remains in Reset until this bit is reset to '0'. The Interrupt Enable bit enables interrupts when the bit is 0. When the bit is 1, interrupts from the CompactFlash Memory Card are disabled. This bit also controls the Int bit in the Configuration and Status Register. This bit is set to 0 at power on and Reset. This bit is ignored by the CompactFlash Memory Card.
4.5.11. Card (Drive) Address Register (Address 3F7[377]; Offset Fh) This register is provided for compatibility with the AT disk drive interface. It is recommended that this register not be mapped into the host's I/O space because of potential conflicts on Bit 7. The bits are defined as follows:
D7 X Bit 7 D6 -WTG D5 -HS3 D4 -HS2 D3 -HS1 D2 -HS0 D1 -nDS1 D0 -nDS0
This bit is unknown. Implementation Note: Conflicts may occur on the host data bus when this bit is provided by a Floppy Disk Controller operating at the same addresses as the CompactFlash Memory Card. Following are some possible solutions to this problem for the PCMCIA implementation: 1. Locate the CompactFlash Memory Card at a non-conflicting address, i.e., Secondary address (377) or in an independently decoded Address Space when a Floppy Disk Controller is located at the Primary addresses. 2. Do not install a Floppy and a CompactFlash Memory Card in the system at the same time.

Bit 6 (-WTG) Bit 5 (-HS3) Bit 4 (-HS2) Bit 3 (-HS1) Bit 2 (-HS0) Bit 1 (-nDS1) Bit 0 (-nDS0)
3. Implement a socket adapter that can be programmed to (conditionally) tri-state D7 of I/0 address 3F7/377 when a CompactFlash Memory Card is installed and conversely to tri-state D6-D0 of I/O address 3F7/377 when a floppy controller is installed. 4. Do not use the CompactFlash Memory Card's Drive Address register. This may be accomplished by either a) If possible, program the host adapter to enable only I/O addresses 1F0-1F7, 3F6 (or 170-177, 176) to the CompactFlash Memory Card or b) if provided use an additional Primary/Secondary configuration in the CompactFlash Card which does not respond to accesses to I/O locations 3F7 and 377. With either of these implementations, the host software must not attempt to use information in the Drive Address Register. This bit is 0 when a write operation is in progress, otherwise, it is 1. This bit is the negation of bit 3 in the Drive/Head register. This bit is the negation of bit 2 in the Drive/Head register. This bit is the negation of bit 1 in the Drive/Head register. This bit is the negation of bit 0 in the Drive/Head register. This bit is 0 when drive 1 is active and selected. This bit is 0 when the drive 0 is active and selected.

5. ATA Command Description
This section defines the software requirements and the format of the commands the host sends to the CompactFlash Memory Cards. Commands are issued to the CompactFlash Card by loading the required registers in the command block with the supplied parameters, and then writing the command code to the Command Register. The manner in which a command is accepted varies. There are three classes (see Table 5-1) of command acceptance, all dependent on the host not issuing commands unless the CompactFlash Card is not busy. (The BUSY bit in the status and alternate status registers is 0.)
* *
*
Upon receipt of a Class 1 command, the CompactFlash Card sets the BUSY bit within 400 nsec. Upon receipt of a Class 2 command, the CompactFlash Memory Card sets the BUSY bit within 400 nsec, sets up the sector buffer for a write operation, sets DRQ within 700 sec, and clears the BUSY bit within 400 nsec of setting DRQ. Upon receipt of a Class 3 command, the CompactFlash Memory Card sets the BUSY bit within 400 nsec, sets up the sector buffer for a write operation, sets DRQ within 20 msec (assuming no reassignments), and clears the BUSY bit within 400 nsec of setting DRQ.

These commands are not standard PC Card ATA commands but provide additional functionality. These commands are not standard PC Card ATA commands and these features are no longer supported with the introduction of 256 Mbit Flash Technology. If one of these commands is issued, the sectors will be erased but there will be no net gain in write performance when using the Write Without Erase command. Definitions: FR = Features Register, SC = Sector Count Register, SN = Sector Number Register, CY = Cylinder Registers, DH = Card/Drive/Head Register, LBA = Logical Block Address Mode Supported (see command descriptions for use). Y--The register contains a valid parameter for this command. For the Drive/Head Register Y means both the CompactFlash Card and head parameters are used; D--only the CompactFlash Card parameter is valid and not the head parameter.

This command checks the power mode. If the CompactFlash Memory Card is in, going to, or recovering from the sleep mode, the CompactFlash Card sets BSY, sets the Sector Count Register to 00h, clears BSY and generates an interrupt. If the CompactFlash Memory Card is in Idle mode, the CompactFlash Card sets BSY, sets the Sector Count Register to FFh, clears BSY and generates an interrupt.

NOTE: The Format Track command in Table 5-6 is no longer recommended. The command is supported to guarantee backward compatibility. This command writes the desired head and cylinder of the selected drive with an FFh pattern. To remain host backward compatible, the CompactFlash Memory Card expects a sector buffer of data from the host to follow the command with the same protocol as the Write Sector(s) command although the information in the buffer is not used by the CompactFlash Card. If LBA=1 then the number of sectors to format is taken from the Sec Cnt register (0=256).

This command causes the CompactFlash Card to set BSY, enter the Idle (Read) mode, clear BSY and generate an interrupt. If the sector count is non-zero, it is interpreted as a timer count with each count being 5 milliseconds and the automatic power down mode is enabled. If the sector count is zero, the automatic power down mode is disabled. Note that this time base (5 msec) is different from the ATA specification. 5.1.7. Idle Immediate--95H, E1H Table 5-14.

This command enables the host to set the number of sectors per track and the number of heads per cylinder. Only the Sector Count and the Card/Drive/Head registers are used by this command. NOTE: SanDisk recommends NOT using this command in any system because DOS determines the offset to the Boot Record based on the number of heads and sectors per track. If a CompactFlash Memory Card is "Formatted" with one head and sector per track value, the same CompactFlash Card will not operate correctly with DOS configured with another heads and sectors per track value.

NOTE: The current revision of the CompactFlash Memory Card only supports a block count of 1 as indicated in the Identify Drive Information command. This command is provided for compatibility with future products that may support a larger block count. The Read Multiple command performs similarly to the Read Sectors command. Interrupts are not generated on every sector, but on the transfer of a block, which contains the number of sectors defined by a Set Multiple, command. Command execution is identical to the Read Sectors operation except that the number of sectors defined by a Set Multiple command is transferred without intervening interrupts. DRQ qualification of the transfer is required only at the start of the data block, not on each sector. The block count of sectors to be transferred without intervening interrupts is programmed by the Set Multiple Mode command, which must be executed prior to the Read Multiple command. When the Read Multiple command is issued, the Sector Count Register contains the number of sectors (not the number of blocks or the block count) requested. If the number of requested sectors is not evenly divisible by the block count, as many full blocks as possible are transferred, followed by a final, partial block transfer. The partial block transfer is for n sectors, where: n = (sector count)--modulo (block count).

ATA Command Description
If the Read Multiple command is attempted before the Set Multiple Mode command has been executed or when Read Multiple commands are disabled, the Read Multiple operation is rejected with an Aborted Command error. Disk errors encountered during Read Multiple commands are posted at the beginning of the block or partial block transfer, but DRQ is still set and the data transfer will take place as it normally would, including transfer of corrupted data, if any. Interrupts are generated when DRQ is set at the beginning of each block or partial block. The error reporting is the same as that on a Read Sector(s) Command. This command reads from 1 to 256 sectors as specified in the Sector Count register. A sector count of 0 requests 256 sectors. The transfer begins at the sector specified in the Sector Number Register. At command completion, the Command Block Registers contain the cylinder, head and sector number of the last sector read. If an error occurs, the read terminates at the sector where the error occurred. The Command Block Registers contain the cylinder, head and sector number of the sector where the error occurred. The flawed data is pending in the sector buffer. Subsequent blocks or partial blocks are transferred only if the error was a correctable data error. All other errors cause the command to stop after transfer of the block that contained the error. 5.1.11. Read Long Sector--22H, 23H Table 5-18. Read Long Sector

The Read Long command performs similarly to the Read Sector(s) command except that it returns 516 bytes of data instead of 512 bytes. During a Read Long command, the CompactFlash Memory Card does not check the ECC bytes to determine if there has been a data error. Only single sector read long operations are supported. The transfer consists of 512 bytes of data transferred in word mode followed by 4 bytes of random data transferred in byte mode. Random data is returned instead of ECC bytes because of the nature of the ECC system used. This command has the same protocol as the Read Sector(s) command.

This command reads from 1 to 256 sectors as specified in the Sector Count register. A sector count of 0 requests 256 sectors. The transfer begins at the sector specified in the Sector Number Register. When this command is issued and after each sector of data (except the last one) has been read by the host, the CompactFlash Memory Card sets BSY, puts the sector of data in the buffer, sets DRQ, clears BSY, and generates an interrupt. The host then reads the 512 bytes of data from the buffer. At command completion, the Command Block Registers contain the cylinder, head and sector number of the last sector read. If an error occurs, the read terminates at the sector where the error occurred. The Command Block Registers contain the cylinder, head, and sector number of the sector where the error occurred. The flawed data is pending in the sector buffer. 5.1.13. Read Verify Sector(s)--40H, 41H Table 5-20. Read Verify Sectors

This command is identical to the Read Sectors command, except that DRQ is never set and no data is transferred to the host. When the command is accepted, the CompactFlash Memory Card sets BSY. When the requested sectors have been verified, the CompactFlash Memory Card clears BSY and generates an interrupt. Upon command completion, the Command Block Registers contain the cylinder, head, and sector number of the last sector verified. If an error occurs, the verify terminates at the sector where the error occurs. The Command Block Registers contain the cylinder, head and sector number of the sector where the error occurred. The Sector Count Register contains the number of sectors not yet verified.

Accepted for backward compatibility with the SDP Series but has no impact on the CF Memory Card. 4 bytes of data apply on Read/Write Long commands. Enable Power on Reset (POR) establishment of defaults at Soft Reset. Operation
Features 01H and 81H are used to enable and clear 8 bit data transfer mode. If the 01H feature command is issued, all data transfers will occur on the low order D7-D0 data bus and the IOIS16 signal will not be asserted for data register accesses. A host can choose the transfer mechanism by Set Transfer Mode and specifying a value in the Sector Count register. The upper 5 bits define the type of transfer and the low order 3 bits encode the mode value.
PIO Default Transfer Mode PIO Flow Control Transfer Mode x Multiword DMA Mode x Reserved Reserved 00000 00d 00001 nnn 00100 nnn 01000 nnn 10000 nnn
Where "nnn" is a valid mode number in binary, "x" is the mode number in decimal for the associated transfer type, and "d" is ignored. Features 55H and BBH are the default features for the CompactFlash Memory Card; thus, the host does not have to issue this command with these features unless it is necessary for compatibility reasons.

ATA Command Description
The 9AH Feature is accepted for backward compatibility with the SDP Series but has no impact on the CompactFlash Memory Card. SanDisk does not recommend the use of this command in new designs. Features 66H and CCH can be used to enable and disable whether the Power On Reset (POR) Defaults will be set when a soft reset occurs. The default setting is to revert to the POR defaults when a soft reset occurs. POR defaults the number of heads and sectors along with 16 bit data transfers and the read/write multiple block count. 5.1.18. Set Multiple Mode--C6H Table 5-27. Seat Multiple Mode

This command enables the CompactFlash Card to perform Read and Write Multiple operations and establishes the block count for these commands. The Sector Count Register is loaded with the number of sectors per block. The current version of the CompactFlash Card supports only a block size of 1 sector per block. Future versions may support larger block sizes. Upon receipt of the command, the CompactFlash Card sets BSY to 1 and checks the Sector Count Register. If the Sector Count Register contains a valid value and the block count is supported, the value is loaded for all subsequent Read Multiple and Write Multiple commands and execution of those commands is enabled. If a block count is not supported, an Aborted Command error is posted, and Read Multiple and Write Multiple commands are disabled. If the Sector Count Register contains 0 when the command is issued, Read and Write Multiple commands are disabled. At power on, or after a hardware or (unless disabled by a Set Feature command) software reset, the default mode is Read and Write Multiple disabled. 5.1.19. Set Sleep Mode- 99H, E6H Table 5-28.

ATA Command Description
This command causes the CompactFlash Memory Card to set BSY, enter the Sleep mode, clear BSY and generate an interrupt. Recovery from sleep mode is accomplished by simply issuing another command (a reset is permitted but not required). Sleep mode is also entered when internal timers expire so the host does not need to issue this command except when it wishes to enter Sleep mode immediately. The default value for the read to sleep timer is 5 milliseconds. Note that this time base (5 msec) is different from the ATA Specification. 5.1.20. Standby--96H, E2H Table 5-29. Standby

ATA Command Description
This command is effectively a NOP command and only implemented for backward compatibility with earlier SanDisk SDP series products. The Sector Count Register will always be returned with an 00H indicating Wear Level is not needed. 5.1.24. Write Buffer--E8H Table 5-34. Write Buffer

The Write Buffer command enables the host to overwrite contents of the CompactFlash Memory Card's sector buffer with any data pattern desired. This command has the same protocol as the Write Sector(s) command and transfers 512 bytes. 5.1.25. Write Long Sector--32H, 33H Table 5-35. Write Long Sector
Bit -> Command (7) C/D/H (6) Cyl High (5) Cyl Low (4) Sec Num (3) Sec Cnt (2) Feature (1) 1 LBA 1 7 6 5 4 32H or 33H Drive Cylinder High (LBA 23-16) Cylinder Low (LBA 15-8) Sector Number (LBA 7-0) X X Head (LBA 27-24) 3 2 1 0
This command is provided for compatibility purposes and is similar to the Write Sector(s) command except that it writes 516 bytes instead of 512 bytes. Only single sector Write Long operations are supported. The transfer consists of 512 bytes of data transferred in word mode followed by 4 bytes of ECC transferred in byte mode. Because of the unique nature of the solid-state CompactFlash Memory Card, the four bytes of ECC transferred by the host cannot be used by the CompactFlash Card. The CompactFlash Card discards these four bytes and writes the sector with valid ECC fields. This command has the same protocol as the Write Sector(s) command.

NOTE: The current revision of the CompactFlash Memory Card only supports a block count of 1 as indicated in the Identify Drive Command information. This command is provided for compatibility with future products that may support a larger block count. This command is similar to the Write Sectors command. The CompactFlash Memory Card sets BSY within 400 nsec of accepting the command. Interrupts are not presented on each sector but on the transfer of a block that contains the number of sectors defined by Set Multiple. Command execution is identical to the Write Sectors operation except that the number of sectors defined by the Set Multiple command is transferred without intervening interrupts. DRQ qualification of the transfer is required only at the start of the data block, not on each sector. The block count of sectors to be transferred without intervening interrupts is programmed by the Set Multiple Mode command, which must be executed prior to the Write Multiple command. When the Write Multiple command is issued, the Sector Count Register contains the number of sectors (not the number of blocks or the block count) requested. If the number of requested sectors is not evenly divisible by the sector/block, as many full blocks as possible are transferred, followed by a final, partial block transfer. The partial block transfer is for n sectors, where: n = remainder (sector count/block count). If the Write Multiple command is attempted before the Set Multiple Mode command has been executed or when Write Multiple commands are disabled, the Write Multiple operation will be rejected with an aborted command error. Errors encountered during Write Multiple commands are posted after the attempted writes of the block or partial block transferred. The Write command ends with the sector in error, even if it is in the middle of a block. Subsequent blocks are not transferred in the event of an error. Interrupts are generated when DRQ is set at the beginning of each block or partial block. The Command Block Registers contain the cylinder, head and sector number of the sector where the error occurred and the Sector Count Register contains the residual number of sectors that need to be transferred for successful completion of the command e.g., each block has 4 sectors, a request for 8 sectors is issued and an error occurs on the third sector. The Sector Count Register contains 6 and the address is that of the third sector.

SanDisk does not recommend the use of this command in new designs but it is supported as a normal Write Sectors command for backward compatibility reasons. 5.1.28. Write Sector(s)--30H, 31H Table 5-38. Write Sectors
Bit -> Command (7) C/D/H (6) Cyl High (5) Cyl Low (4) Sec Num (3) Sec Cnt (2) Feature (1) 1 LBA 1 7 6 5 4 30H or 31H Drive Cylinder High (LBA 23-16) Cylinder Low (LBA 15-8) Sector Number (LBA 7-0) Sector Count X Head (LBA 27-24) 3 2 1 0
This command writes from 1 to 256 sectors as specified in the Sector Count Register. A sector count of zero requests 256 sectors. The transfer begins at the sector specified in the Sector Number Register. When this command is accepted, the CompactFlash Memory Card sets BSY, then sets DRQ and clears BSY, then waits for the host to fill the sector buffer with the data to be written. No interrupt is generated to start the first buffer fill operation. No data should be transferred by the host until BSY has been cleared by the host. For multiple sectors, after the first sector of data is in the buffer, BSY will be set and DRQ will be cleared. After the next buffer is ready for data, BSY is cleared, DRQ is set and an interrupt is generated. When the final sector of data is transferred, BSY is set and DRQ is cleared. It will remain in this state until the command is completed at which time BSY is cleared and an interrupt is generated. If an error occurs during a write of more than one sector, writing terminates at the sector where the error occurs. The Command Block Registers contain the cylinder, head and sector number of the sector where the error occurred. The host may then read the command block to determine what error has occurred, and on which sector.
