Description
Register Access: During PC Card memory cycles,
this output chooses between Attribute and Common
Memory. During I/O cycles for non-DMA transfers,
this signal is active (low). During ATA mode, this
signal is always inactive. For DMA cycles on the
OZ6812 to a DMA-capable card, REG# becomes
DACK to the PCMCIA card.
CardBus Command Byte Enable: In CardBus
mode, this pin is the CCBE3#.
Address: PC Card socket address 25:24 outputs.
CardBus Address/Data: CardBus mode, these pins
are the CAD bits 19 and 17.
Address: PC Card socket address 23 output.
CardBus Frame: In CardBus mode, this pin is the
CFRAME# signal.
Address: PC Card socket address 22 output.
CardBus Target Ready: In CardBus mode, this pin
is the CTRDY# signal.
Address: PC Card socket address 21 output.
CardBus Device Select: In CardBus mode, this pin
is the CDEVSEL# signal.
Address: PC Card socket address 20 output.
CardBus Stop: In CardBus mode, this pin is the
CSTOP# signal.
Address: PC Card socket address 19 output.
CardBus Lock: In CardBus mode, this signal is the
CBLOCK# signal used for locked transactions.
Address: PC Card socket address 18 output.
Reserved: In CardBus mode, this pin is reserved for
future use.
Address: PC Card socket address 17 output.
CardBus Address/Data: In CardBus mode, this pin
is the CAD bit 16.
Address: PC Card socket address 16 output.
