Description: These registers contain the high six bits of the 16-bit memory window offset address for
memory windows 0, 1, 2, 3 and 4. The lower six bits of these registers correspond to bits
A25-A20 of the offset address. In addition, the write protection and common/attribute memory
configurations are set in this register. See Table 49 for a complete description of the register
contents.
Read only, read/write (see individual bit descriptions)
