I/O
CardBus address and data. These signals make up the multiplexed CardBus address
and data bus on the CardBus interface. During the address phase of a CardBus cycle,
CAD31CAD0 contain a 32-bit address. During the data phase of a CardBus cycle,
CAD31CAD0 contain data. CAD31 is the most significant bit.

I/O
CardBus bus commands and byte enables. CC/BE3CC/BE0 are multiplexed on the
same CardBus terminals. During the address phase of a CardBus cycle,
CC/BE3CC/BE0 define the bus command. During the data phase, this 4-bit bus is used
as byte enables. The byte enables determine which byte paths of the full 32-bit data bus
carry meaningful data. CC/BE0 applies to byte 0 (CAD7CAD0), CC/BE1 applies to
byte 1 (CAD15CAD8), CC/BE2 applies to byte 2 (CAD23CAD16), and CC/BE3
applies to byte 3 (CAD31CAD24).

I/O
CardBus parity. In all CardBus read and write cycles, the PCI1520 calculates even parity
across the CAD and CC/BE buses. As an initiator during CardBus cycles, the PCI1520
outputs CPAR with a one-CCLK delay. As a target during CardBus cycles, the PCI1520
compares its calculated parity to the parity indicator of the initiator; a compare error
results in a parity error assertion.
Terminal name for slot A is preceded with A_. For example, the full name for terminals 107 and P15 is A_CPAR.
Terminal name for slot B is preceded with B_. For example, the full name for terminals 40 and N02 is B_CPAR.
