NOTES:
1. To differentiate the sockets, all socket-specific pins have either A_ or B_ prepended to the pin names indicated. For example,
2. When a socket is configured as an ATA drive interface, socket interface pin functions change. See

Socket Interface Pins (Sheet 1 of 3)
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.
PCMCIA socket address outputs.
PCMCIA socket data I/O pins.
Output Enable: This output goes active
(low) to indicate a memory read from the
PCMCIA socket to the PD6729.
Write Enable: This output goes active
(low) to indicate a memory write from the
PD6729 to the PCMCIA socket.
I/O Read: This output goes active (low) for
I/O reads from the socket to the PD6729.
I/O Write: This output goes active (low) for
I/O writes from the PD6729 to the socket.
Write Protect / I/O Is 16-Bit: In Memory
Card Interface mode, this input is
interpreted as the status of the write
protect switch on the PCMCIA card. In I/O
Card Interface mode, this input indicates
the size of the I/O data at the current
address on the PCMCIA card.
Input Acknowledge: The -INPACK
function is not applicable in PCI bus
environments. It is, however, advisable to
connect this pin to the PC Card socket’s -
INPACK pin.
