Pin
Driven by the host to strobe memory write data to the
registers.
Used for writing to the configuration registers.
Not used, should be connected to V
No write protect switch available. It is held Low after the
completion of the reset initialization sequence.
Used for the 16 bit port (–IOIS16) function. Low indicates
that a 16 bit or odd byte only operation can be performed
at the addressed port.
Asserted Low when the card is expecting a word data
transfer cycle.
