SLBASE32_PCI
Slave's Base Address for PCI access. Specifies the lowest address
in the VME address range that will be decoded. Since only
A[31:20] are monitored, the smallest possible address space is
1 MB.
Default: 000000000000

PCI_OFFSET
4-kbyte aligned offset address on PCI bus for VME-to-PCI
accesses.
The PCI space is accessible via A24 and A32 access on the
VMEbus. To do this, the SLV24_PCI or SLV32_PCI control
registers must be set.
