Register Access:
In Memory Card
Interface mode, this output chooses
between attribute and common mem-
ory. In I/O Card Interface mode for
non-DMA transfers, this signal is active
(low).
For DMA cycles on the CL-PD6722 to
a DMA-capable card, -REG is inactive
during I/O cycles to indicate a DMA
cycle to or from the PC Card.
In ATA mode, this signal is always
inactive.

-OE
Output Enable
: For non-DMA trans-
fers, this output goes active (low) to
indicate a memory read from the
socket.
During a DMA write (when -IORD is
active) this output goes low if the ISA
output TC is active (high), indicating to
the card that the system’s terminal
count signal is active. During DMA
reads (when -IOWR is active), this out-
put remains high.

To differentiate the sockets, all CL-PD6722 pin names 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.

When a socket is configured as an ATA drive interface, socket interface pin functions change. See
Table 11-1 on page 75
