Setting PULSED
In this mode, pressing the function key for minimum 0.5 seconds (detection period, not changeable)
changes the output to 1 (high). After a time defined by PulseTime, the output will return to 0 (low)
irrespective of the status of the function key.
If the function key is pressed again, a new pulse will be generated only if the output is 0 at the end of
the detection period. See

OFF) of the yellow LED on the function key directly follows the status of LEDCTL. This functionality is
independent of the Mode setting.
