11.3.2.4 Memory Mapping Window Control Registers
M68HC11K Family
MOTOROLA
Address: $0058
Address: $0059
Each of the memory mapping window control registers (MM1CR and
MM2CR) determine the active memory bank for the corresponding
window, containing the value to be output on the expansion address
lines when the CPU selects addresses within its extended memory
window. To change banks, write the address of the new bank into the
appropriate window register.

Each bit value written to the MMxCR registers is driven on the
corresponding port G expansion address line (if enabled by PGAR) to
enable the specified bank in the window.
