(15) PCI Memory Base Address Register 1 (PCIMBAR1)
This register is the memory base address register of the PCI configuration register space header
that is defined in PCI local bus specification. PCIMBAR1 specifies the memory space 1 (local
address space 1) in this LSI internal bus (SuperHyway bus).
See section 13.4.4 (1), Accessing Memory Space in This LSI.

Description
Memory Space 1 Base Address (upper 12 bits)
These bits specify the upper 12 bits of memory base
address for the local address space 1 (the address
space in the internal bus).
The valid bits of MBA1 depend on the capacity of the
local address space specified with LSR in PCILSR1.
