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, CAD31–CAD0
contain a 32-bit address. During the data phase of a CardBus cycle, CAD31–CAD0 contain data.
CAD31 is the most significant bit.

I/O
CardBus bus commands and byte enables. CC/BE3–CC/BE0 are multiplexed on the same
CardBus terminals. During the address phase of a CardBus cycle, CC/BE3–CC/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 (CAD7–CAD0), CC/BE1 applies to byte 1 (CAD15–CAD8), CC/BE2 applies to byte 2
(CAD23–CAD16), and CC/BE3 applies to byte 3 (CAD31–CAD24).
CPAR

G15
I/O
CardBus parity. In all CardBus read and write cycles, the PCI1410 calculates even parity across
the CAD and CC/BE buses. As an initiator during CardBus cycles, the PCI1410 outputs CPAR
with a one-CCLK delay. As a target during CardBus cycles, the calculated parity is compared to
the initiator’s parity indicator; a compare error results in a parity error assertion.
