Function
TRANSITION COUNTER
TCNT
(123)
TCNT N S
Computes the number of times that a
transition program is executed and turns ON
the Transition Flag when the preset count is
reached. Each counter number (BCD) can be
used in only one counter instruction (CNT,
CNTR(012), and TCNT(123)), unless the
counters are never active simultaneously.
