Explanation:
1. The instruction is used to compare n pieces of data in devices starting from S
devices starting from S
comparison results are stored in D.
2. The operand n should be within the range between 1 and 256.
3. The value which is written into the operand D is a one-bit value.
4. When the results gotten from the comparison by using the instruction CMPT# are that all
devices are ON, SM620 is ON. Otherwise, SM620 is OFF.
5. If the operand S is a device, the comparison will be as shown below.
