Memory Base Address
Hardwired to 0
PRE
Type
0
This register can be used to relocate memory address space to any location that is aligned to 4K bytes for mapping W6692A's
internal registers.
Bits 31-12
Memory Base Address
R/W
These bits are read/write and are used to relocate the memory address space at 4K byte boundary.
Bits 11-4
Read_only
These bits are read_only and are hardwired to 0.
Bit 3
Prefetchable
Read_only
This bit is hardwired to 0 if EEPROM is empty. Otherwise, it is loaded from EEPROM.
Bits 2-1
Type
Read_only
These two bits are hardwired to 00, indicating the memory range can locate anywhere in 32 bit address space.
Bit 0
Memory Space Indicator
Read_only
This bit is hardwired to 0, indicating a memory space is allocated.

This register can be used to relocate I/O address space to any location that is aligned to 256 bytes for mapping W6692A's
internal registers.
Bits 31-8
IO Base Address
R/W
These bits are read/write and are used to relocate the IO address space at 256 byte boundary.
Bits 7-2
Read_only
These bits are read_only and are hardwired to 0.
Bit 1
Reserved
Read_only
This bit is reserved and is hardwired to 0.
Bit 0
IO Space Indicator
Read_only
This bit is hardwired to 1, indicating a I/O space is allocated.
