TIMERS
The 3826 group has five timers: timer X, timer Y, timer 1, timer 2,
and timer 3. Timer X and timer Y are 16-bit timers, and 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 contin-
ued. When a timer underflows, the interrupt request bit corre-
sponding to that timer is set to “1”.
Read and write operation on 16-bit timer must be performed for
both high- and low-order bytes. When reading a 16-bit timer, read
the high-order byte first. When writing to a 16-bit timer, write the
low-order byte first. The 16-bit timer cannot perform the correct
operation when reading during the write operation, or when writing
during the read operation.
