MMOV, MMOVP: 5 steps
Operands:
S: Source device (16-bit) D: Destination device (32-bit)
Explanations:
MMOV instruction sends the data in 16-bit device S to 32-bit device D. Sign bit (MSB) of source device will be
copied to every bit in the high byte of D.
Program Example:
When X23 = 0N, 16-bit data in D4 will be sent to D6 and D7.

In the example above, b15 in D4 will be sent to b15~b31 of D7/D6, therefore all bits form b15~b31 will be “negative.”
