MBARA—Memory Base Address Register A
(Gigabit LAN—D25:F0)
Address Offset: 10h
Default Value:
The internal CSR registers and memories are accessed as direct memory mapped
offsets from the base address register. SW may only access whole DWord at a time.
MBARB—Memory Base Address Register B
(Gigabit LAN—D25:F0)
Address Offset: 14h
Default Value:
The internal registers that are used to access the LAN Space in the External FLASH
device. Accessed to these registers are direct memory mapped offsets from the base
address register. SW may only access a DWord at a time.
