These bits are read/write and are used to relocate the memory address space at 4K byte boundary.
These bits are read_only and are hardwired to 0
This bit is hardwired to 0 if EEPROM is empty. Otherwise, it is loaded from EEPROM.
These two bits are hardwired to 00, indicating the memory range can locate anywhere in 32 bit address space.
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 W6692's internal
These bits are read/write and are used to relocate the IO address space at 256 byte boundary.
