MULTIJUNCTION TIMERS
10.3 TOP (Output-related 16-bit Timer)
In the example below, the counter has the initial value H'A000 set in it and the reload register has
the initial value H'F000 set in it. When the timer starts, the counter starts counting down clock
pulses and when it underflows after reaching the minimum count, the counter is reloaded with the
content of the reload register. Then when the counter underflows next time while continuing down-
count, it stops.
