FREE MEMORY AVAILABLE This register can
be read at any time to determine the amount of
free memory. The register defaults to the
MEMORY SIZE upon reset or upon the RESET
MMU command.
All memory-related information is represented in
256 * M byte units, where the multiplier M is
determined by the MCR upper byte.
These registers default to FFh, which should be
interpreted as 256.
MEMORY SIZE - This register can be read to
determine the total memory size.
