duration of the time-to-go (MN).
Input En En is the monitoring input. xLogic scans the on-time of this
input.
Input Ral A positive edge at input Ral (Reset all) resets both the hours
counter (OT) and the output, and sets the configured value
MI at the counter to for the duration of the time-to-go (MN).


When "R" is selected:
Q = 1, if MN = 0;
Q = 0, if R = 1 or Ral = 1

When "R+En" is selected:
Q = 1, if MN = 0;
Q = 0, if R = 1 or Ral = 1 or En = 0.
Output Q The output is set when the time-to-go MN = 0. The output is
reset:

When "Q 0:R+En", if
R = 1 or Ral = 1 or En = 0

When "Q 0:R",
if R = 1 or Ral = 1.
