I/O
PCI address/data bus. These signals make up the multiplexed PCI address and data bus on the primary
interface. During the address phase of a primary bus PCI cycle, AD31-AD0 contain a 32-bit address or
other destination information. During the data phase, AD31-AD0 contain data.

I/O
PCI bus commands and byte enables. These signals are multiplexed on the same PCI terminals. During
the address phase of a primary bus PCI cycle, C/BE3–C/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. C/BE0 applies to byte 0 (AD7–AD0), C/BE1 applies to byte 1
(AD15–AD8), C/BE2 applies to byte 2 (AD23–AD16), and C/BE3 applies to byte 3 (AD31–AD24).
PAR
202
C6
I/O
PCI bus parity. In all PCI bus read and write cycles, the PCI1221 calculates even parity across the
AD31–AD0 and C/BE3–C/BE0 buses. As an initiator during PCI cycles, the PCI1221 outputs this parity
indicator with a one-PCLK delay. As a target during PCI cycles, the calculated parity is compared to the
initiator’s parity indicator. A compare error results in the assertion of a parity error (PERR).
