(3) Accessing PCI I/O Space
Access within the size of 4-byte.
Burst I/O transfers are not supported.
The PCI I/O address space is allocated from H'FD20 0000 to H'FE3F FFFF (2 Mbytes).
Address translation from SuperHyway bus to PCI local bus
The lower 15 bits ([17:3]) of a SuperHyway bus address are sent without translation.
Bits 20 to 18 of a SuperHyway bus address are controlled by the PCI I/O bank mask register
(PCIIOBMR).
Note: In the following item and figure, “SH” means the SuperHyway bus of this LSI and “PCI”
means the PCI local bus.
•
PCIIOMR0 [20:18] B'111: PCI address [20:18] = SH address [20:18]
•
PCIIOMR0 [20:18] B'011: PCI address [20:18] = PCIIOBR [20], SH address [19:18]
•
PCIIOMR0 [20:18] B'001: PCI address [20:18] = PCIIOBR [20:19], SH address [18]
•
PCIIOMR0 [20:18] B'000: PCI address [20:18] = PCIIOBR [20:18]
The upper 11 bits ([31:21]) of a SuperHyway bus address are replaced with bits 31 to 21 in the
PCI I/O bank register (PCIIOBR).
