Mx: Modify Byte, Longword, Register, Word
Command:
MB, ML, MR, MW
Syntax:
MB <addr>

Purpose:
Modify byte, word, longword, or register. These
commands allow bytes, words, or longwords to be displayed
or modified. For MR, all CPU registers are displayed
starting at D0. Continually hitting <cr> will display a new
register until it wraps. For MB, MW, or ML, hitting <cr>
will increment the address by the appropriate amount.
Entering a comma will decrement the address. If the
address is not mapped to a chip select the monitor will
print: No chip select for address <address> and the
monitor will abort the command. To change the value of a
register or RAM location, enter the new value to the right
of the display. All input is in Hex.
