slfld25-xxxj(i) ide flash drive document part number 61000-02817-109 march 2005 page 18 idle (code: e3h or 97h) this command causes the drive to set bsy, enter the idle mode, clear bsy, and generate an interrupt. if the sector count is non-zero, automatic power down mode is enabled. if the sector count is zero, the automatic power down mode is disabled. idle immediate (code: e1h or 95h) this command causes the drive to set bsy, enter the idle (read) mode, clear bsy, and generate an interrupt. initialize drive parameters (code: 91h) this command enables the host to set the number of sectors per track and the number of heads per cylinder. read buffer (code: e4h) this command enables the host to read the current contents of the drive?s sector buffer. read multiple (code: c4h) this command performs similarly to the read sectors command. interrupts are not generated on each sector, but on the transfer of a block which contains the number of sectors defined by a set multiple command. read long sector (code: 22h or 23h) this command performs similarly to the read sector(s) command except that it returns 516 bytes of data instead of 512 bytes. read sector(s) (code: 20h or 21h) 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. read verify sector(s) (code: 40h or 41h) this command verifies one or more sectors on the drive by transferring data from the flash media to the data buffer in the drive and verifying that the ecc is correct. this commandis identical to the read sectors command, except that drq is never set and no data is transferred to the host. this recalibrate (code: 1xh) the comapactflash performs only the interface timing and register operations. when this command is issued, the comapactflash sets bsy and waits for an appropriate length of time after which it clears bsy and issues an interrupt. when this command ends normally, the comapactflash is initialized request sense (code: 03h) this command requests an extended error code after a command ends with an error. refer to table below. code description 00h no error detected 01h self test ok (no error) 09h miscellaneous error - n/a 20h invalid command 21h invalid address (requested head or sector invalid) 2fh address overflow (address too large) 35h, 36h supply or generate voltage out of tolerance 11h uncorrectable ecc error 18h correctable ecc error - n/a 05h, 30h-34h, 37h, 3eh self test diagnostic failed 10h, 14h id not found - n/a 3ah spare sectors exhausted 1fh data transfer error / aborted command 0ch, 38h, 3bh, 3ch, 3fh corrupted media format - n/a 03h write / erase failed - n/a 22h power level 1 disabled serial number format (typical): words 10-19 simpletech proprietary yr day hr min sec sti_j13c0 04 224 09 27 50 firmware revision: words 23-26 mm/dd/yy model number: words 27-46 sti flash x.y.z identify drive information (continued) (serial number, firmware revision, and model number)
slfld25-xxxj(i) ide flash drive document part number 61000-02817-109 march 2005 page 19 seek (code: 7xh) this command is effectively a nop command to the drive although it does perform a range check. set features (code: efh) this command is used by the host to establish or select certain features. feature description 01h enable 8-bit data transfers 55h disable read look ahead 66h disable power on reset (por) establishment of defaults at soft reset 81h disable 8-bit data transfers bbh 4bytes of data apply on read/write long commands cch enable power on reset (por) establishment of default at soft reset set multiple mode (code: c6h) this command enables the drive to perform read and write multiple operations and establishes the block count for these commands. set sleep mode (code: e6h or 99h) this is the only command that allows the host to set the comapactflash into sleep mode. when the drive is set to sleep mode, the comapactflash clears the bsy line and issues an interrupt. the drive enters sleep mode and the only method to make the drive active again (back to normal operation) is by performing a hardware reset or a software reset. stand by (code: e2h or 96h) this command sets the drive in standby mode. if the sector count register is a value other than 0h, an auto power down is enabled and when the drive returns to the idle mode, the timer starts a countdown. the time is set in the sector count register. stand by immediate (code: e0h or 94h) this command causes the drive to set bsy, enter the standby mode, clear bsy and return the interrupt immediately. translate sector (code: 87h) this command allows the host a method of determining the exact number of times a user sector has been erased and programmed. this command is not supported. wear level (code: f5h) this command is effectively a nop command and only implemented for backward compatibility. the sector count register will always be returned with an 00h indicating wear level is not needed. write buffer (code: e8h) this command enables the host to overwrite the contents of the drive?s sector buffer with any data pattern desired. write long sector (code: 32h or 33h) 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. write multiple (code: c5h) this command is similar to the write sectors command. interrupts are not presented on each sector, but on the transfer of a block which contains the number of sectors defined by set multiple command. write multiple without erase (code: cdh) this command is similar to the write multiple command with the exception that an implied erase before the write operation is not performed. note that before using this command, it is required to erase the repective sectors using the erase sectors command.
slfld25-xxxj(i) ide flash drive document part number 61000-02817-109 march 2005 page 20 write sector(s) (code: 30h or 31h) 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. write sector(s) without erase (code: 38h) this command is similar to the write sector(s) command with the exception that an implied erase before the write operation is not performed. note that before using this command, it is required to erase the repective sectors using the erase sectors command. write verify (code: 3ch) this command is similar to the write sector(s) command except each sector is verified immediately after being written.
