Description
H'000000 SH: R/W I/O Space Base Address (upper 24 bits)
PCI: R/W Specifies the upper 24 bits of I/O base address that
corresponds the PCIC local register space (PCIC
control register space).
000000 SH: R I/O Space Base Address (lower 6 bits)
PCI: R These bits are fixed 000000 by hardware.
0
SH: R Reserved
PCI: R
These bits are always read as 0. The write value
should always be 0.
1
SH: R Address Space Indicator
PCI: R
Indicates whether the base address in this register
indicates the I/O or memory space.
0: Memory space
1: I/O space
