Explanation of function and operation
1) This function compares the contents of devices specified in
expressed as the bit type data to a device specified in
This function executes comparison [
a) This function outputs "TRUE" when all comparison results are "
b) This function outputs "FALSE" when any comparison result is "
2) The number of pins in
Cautions
When handling 32-bit data in structured programs, you cannot specify 16-bit devices directly, different from
simple projects. Use labels when handling 32-bit data.
You can specify 32-bit counters directly, however, because they are 32-bit devices.
Use global labels when specifying labels.
