2.2.3 True IDE Mode
The card can be configured in a True IDE Mode of operation. This card is configured in this mode only when the –
OE input signal is asserted GND by the host. In this True IDE Mode Attribute Registers are not accessible from the
host. Only I/O operation to the task files and data registers are allowed. If this card is configured during power on
sequence, data registers are 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.
