This card is configured in this mode only when the OE# input signal is asserted to GND by the host during power on . In this True IDE mode Attribute Registers are not accessible from the host. Only I/O operation to the task file and data register is allowed. If this card is configured during power on sequence, data register is accessed in word (16-bit). The card permits 8-bit accesses if the user issues a Set Feature Command to put the device in 8-bit mode.

After confirmation that CD1#, CD2# pins are set, VCC may be supplied to the card. • OE# must be kept at the VCC level during power on reset in memory card mode and I/O card mode.
