Dump (read) memory based on operand
size (sz) and report status. Used with
READ_MEM{_WS} to dump large blocks of
memory. An initial READ_MEM{_WS} is
executed to set up the starting address of
the block and to retrieve the first result.
Subsequent DUMP_MEM{_WS}
commands retrieve sequential operands.
Fill (write) memory based on operand size
(sz). Used with WRITE_MEM to fill large
blocks of memory. An initial WRITE_MEM
is executed to set up the starting address of
the block and to write the first operand.
Subsequent FILL_MEM commands write
sequential operands.
