11.3.2.3 Memory Mapping Window Base Register
Technical Data
236
Address: $0057
The memory mapping window base register (MMWBR) defines the
starting address of each of the two windows within the CPU 64-Kbyte
address range. The windows normally begin at a boundary related to
their size (an 8-Kbyte window can begin on any 8-Kbyte boundary,
beginning at $0000).
