3. The instruction stores the pulse width detection time (32-bit value) in D
the value is over the maximum value, it is processed as the maximum value. If the value is 0, that means is no input
switched from ON to OFF during the execution of this instruction.
4. D is the update flag. Whenever the detection of the S

updated flag switches to ON for one scan cycle time. You can check if the detection value has been updated with
the update flag. When the system executes the instruction for the first time, the update flag resets to OFF.
