5.2 BASE ADDRESS REGISTER

BIF provides a single Base Address Register. The Base Address Register is a 32 bit register that is used to access the BIF

register set. Bits 3:0 are hard-wired to 0 to indicate memory space. Bits 15-4 will be hard-wired to 0. The remaining bits (31 -

16) will be read/write. This specifies that this device requires a 64k byte address space. After reset, the Base Address

Register contains 0x00000000.

The 64k byte address space used by the BIF is divided into 4k-byte regions. Each 4k-byte region is used as Table 5-6.
