TIMERS
The 7510 group has five built-in timers: timer X, timer Y, timer 1,
timer 2, and timer 3. Timer X and timer Y are 16-bit timers,
whereas timer 1, timer 2, and timer 3 are 8-bit timers.
All timers are down count timers. When the timer reaches “0016”,
an underflow occurs at the next count pulse and the correspond-
ing timer latch is reloaded into the timer and the count is
continued. When a timer underflows, the interrupt request bit cor-
