  When XnoA is rising-triggered to start timing, the Exe flag will be ON.
  When XnoB is rising-triggered to stop timing, the Exe flag will be OFF and stores the timed result in PhaseT.
Example
When M0 is ON, the instruction is executed. This instruction calculates the phase time difference between X0.1 and X0.0
and stores the timed result in D0. (The timed result here is 13790 us.)
