Description
TIMER
Times the period elapsed from when INPUT A is set TRUE and held TRUE,
to when INPUT B becomes TRUE.
OUTPUT is the duration of the timer in seconds (1 = 1 second), starting from
zero. If INPUT B is TRUE, the value for OUTPUT is held until INPUT B is
released. If on release INPUT A is still TRUE, the timer will continue from
the held value. Setting INPUT A and INPUT B to FALSE resets the timer.
INPUT C is not used.
