1.2 Recommended Connection of Unused Pins (1) System interface pins (a) 32-bit bus mode The VR5500 allows selection of a SysAD bus width from 64 bits or 32 bits. When the 32-bit bus mode is selected, the VR5500 operates using only the required system interface pins. Therefore, set the unused pins as follows when operating the VR5500 in the 32-bit bus mode.
Pin Name Recommended Connection of Unused Pins SysAD(63:32) SysADC(7:4) Leave open Leave open
(b) Normal mode The VR5500 can process read/write transactions regardless of the order in which requests are issued in the out-of-order return mode. The SysID(2:0) signals are used to identify each request during this processing. Set these signals, which are not used in the normal mode, as follows.
Pin Name Recommended Connection of Unused Pins SysID(2:0) Leave open
(c) Parity bus The VR5500 allows selection of whether the data is protected using parity. When parity is used, the parity data is output from the processor or external agent to the SysADC bus. However, whether the parity is used or not is selected by software, so unless the program is started, the VR5500 cannot determine the operation of the SysADC bus. Therefore, care must be taken to prevent the SysADC bus from being left open or in a high-impedance state. Each pin of the SysADC bus should be connected to VDDIO via a high resistance value resistor when parity is not used.

(2) Test interface pins The VR5500 can be used to perform testing and debugging via N-Wire and JTAG with the device mounted on the board. The test interface pins are used for connection with the external debug tool during this debugging. When this test interface is not going to be used and when it is in normal operation mode, set the test interface pins as follows.

NOTES FOR CMOS DEVICES
1 PRECAUTION AGAINST ESD FOR SEMICONDUCTORS Note: Strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and ultimately degrade the device operation. Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it once, when it has occurred. Environmental control must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using insulators that easily build static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work bench and floor should be grounded. The operator should be grounded using wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with semiconductor devices on it. 2 HANDLING OF UNUSED INPUT PINS FOR CMOS Note: No connection for CMOS device inputs can be cause of malfunction. If no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected to VDD or GND with a resistor, if it is considered to have a possibility of being an output pin. All handling related to the unused pins must be judged device by device and related specifications governing the devices. 3 STATUS BEFORE INITIALIZATION OF MOS DEVICES Note: Power-on does not necessarily define initial status of MOS device. Production process of MOS does not define the initial operation status of the device. Immediately after the power source is turned ON, the devices with reset function have not yet been initialized. Hence, power-on does not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the reset signal is received. Reset operation must be executed immediately after power-on for devices having reset function.
