The PCICONF5 register is initialized to H'00000000 at a power-on reset and software reset.
Always write to this register before transferring data to and from the PCIC memory from the PCI
bus.
Bits 31 to 20—Base Address of the Memory Space 0 (BASE0 31 to 20): These bits specify the
base address of the local address space 0 (this LSI external bus space).
Bits 19 to 4—Base Address of the Memory Space 0 (BASE0 19 to 4): Fixed at H'0000 in
hardware.
Bit 3—Pre-fetch Control (LA0PREF): Shows availability of prefetching of the local address
space 0.
Bit 3: LA0PREF

Bits 2 and 1—LA0TYPE1 and 0: In the case of I/O space, can be set as the base address. Shows
the memory type of the local address space 0.
