Register Access: In Memory Card
Interface mode, this output chooses
between attribute and common memory. In
I/O Card Interface mode, this signal is
active (low).
In ATA mode this signal is always high.

Card Interface mode, this input indicates
the size of the I/O data at the current
address on the PCMCIA card.

NOTES:
1. To differentiate the sockets, all socket-specific pins have either A_ or B_ prepended to the pin names indicated. For example,
A_A[25:0] and B_A[25:0] are the independent address buses to the sockets.
2. When a socket is configured as an ATA drive interface, socket interface pin functions change. See “ATA Mode Operation” on
page 91.
