Memory Module Program Compare
When this bit is set (1) in the controller, its user program and the memory
module user program must match for the controller to enter an executing
mode.
If the user program does not match the memory module program, or if
the memory module is not present, the controller faults with error code
0017H on any attempt to enter an executing mode.
