Chip Select 5 through the LocalPlus Bus. Any access on an address between the Start
and Stop Addresses enables this chip select.
Boot Addressing through the LocalPlus Bus. Any access on an address between the
Start and Stop Addresses accesses the boot space. By default, the address space
accessed starts at 0x0000 0000 or 0xFFF0 0000 depends on the reset configuration.
The size of the boot address space after reset is 512Kbytes.
Chip Select 6 through the LocalPlus Bus. Any access on an address between the Start
and Stop Addresses enables this chip select.
Chip Select 7 through the LocalPlus Bus. Any access on an address between the Start
and Stop Addresses enables this chip select.

These bits are reserved.
The 16 most significant bits of the Base Address. A value of 0x4000 would translate into a
base address of 0x4000 0000.
Contains the Base Addresses and configurations for SDRAM's connected to the
SDRAM controller.
