Section 13 PCI Controller (PCIC)
When all the MBARE bits in PCILSR0/1 are 0, the PCI local bus address is sent to the
SuperHyway bus without translation.
Data prefetching for memory read commands is supported. When a PCI burst read is performed, 8
bytes, or 32 bytes of data block is prefetched. (this depends on the settings of the PFE and PFCS
bits in PCICR).
(2)
Allocate a 256-byte area to the I/O address space.
Address translation from PCI local bus to SuperHyway bus
The lower 8 bits ([7:0]) are sent to the SuperHyway bus without translation.
When bits 31 to 8 of a PCI local bus address match bits 31 to 8 in a PCI I/O base address register
(PCIIBAR), the upper 24 bits of a PCI local bus address are replaced with H'FE04 01.
