Figure 13.15 Address Generation for Type 0 Configuration Access
In configuration accesses, a PCI master abort (no device connected) will not cause an interrupt.
Configuration writes will end normally. Configuration reads will return a value of 0.
(3) Special Cycle Generation
When the PCIC operates as the host device, a special cycle is generated by setting H'8000 FF00 in
the PCIPAR and writing to the PCIPDR.
(4) Arbitration
In host bus bridge mode, the PCI bus arbiter in the PCIC is activated.
The PCIC supports four external masters (i.e., four REQ and GNT pairs).
If use of the bus is simultaneously requested by more than one device, the bus is granted to the
device with the highest priority.
The PCI bus arbiter supports two modes to determine the priority of devices: fixed priority and
pseudo-round-robin. The mode is selected by the BMAM bit in PCICR.
Fixed Priority:
When the BMAM bit in PCICR is cleared to 0, the priorities of devices are fixed
the following default values.
PCIC > device 0 > device 1 > device 2 > device 3
The PCIC always gains use of the bus over other devices.
Pseudo-Round-Robin:
When the BMAM bit in PCICR is set to 1, the most recently granted
device is assigned the lowest priority.
The initial priority is the same as the fixed priority mode.
