3. TRUE IDE MODE
WED7PxxxATA70xxI25
The card can be configured in a True IDE. 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.
