Description
Output Enable: This output goes
active(low) to indicate a memory read from
the PCMCIA socket to the CL-PD6832. In
CardBus mode, this pin is the Cardbus
address/data bit 11.
Write Enable: This output goes active(low)
to indicate a memory write from the CL-
PD6832 to the PCMCIA socket. In CardBus
mode, this pin is the CardBus GNT# signal.
I/O Read: This output goes active (low) for
l/O reads from the socket to the CL-
PD6832. In CardBus mode, this pin is the
CardBus address/data bit 13.
I/O Write: This output goes active (low) for
l/O writes from the CL-PD6832 to the
socket. In CardBus mode, this pin is the
CardBus address/data bit 15.
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 l/O Card
Interface mode, this input indicates the size
of the l/O data at the current address on the
PCMCIA card. In CardBus mode, this pin is
the CardBus CLKRUN# signal, which starts
and stops the CardBus clock CCLK.
Input Acknowledge: The -INPACK
function is not applicable in PCI bus
environments. However, for compatibility
with other Cirrus Logic products, this pin
should be connected to the PCMCIA
socket's -INPACK pin. In CardBus mode,
this pin is the CardBus REQ# signal.
Ready / Interrupt Request: In Memory
Card Interface mode, this input indicates to
the CL-PD6832 that the card is either ready
or busy. In l/O Card Interface mode, this
input indicates a card interrupt request. In
CardBus mode, this pin is the CardBus
Interrupt Request signal. This signal is
active-low and level-sensitive.
Wait: This input indicates a request by the
card to the CL-PD6832 to halt the cycle in
progress until this signal is deactivated. In
CardBus mode, this pin is the CardBus
SERR# signal.
