The lower 8 bits of the timer (interrupt) cycle are set by
the timer register TREG0, and the upper 8 bits are set
by TREG1. Note that TREG0 always must be set first.
(Writing data into TREG0 disables the comparator
temporarily, and the comparator is restarted by writing
data into TREG1.)
Setting example: To generate interrupt INTT1 every
0.5 seconds at fc = 16MHz, set the
following values for timer registers
TREG0 and TREG1.

The comparator match signal is output from timer 0 each
time the up-counter matches UC0, where the up-counter UC0
is not cleared.
With the timer 1 comparator, the match detect signal is
output at each comparator timing when up-counter UC1 and
TREG1 values match. When the match detect signal is output
simultaneously from both comparators of timer 0 and timer 1,
the up-counters UC0 and UC1 are cleared to “0”, and the
interrupt INTT1 is generated. If inversion is enabled, the value
of the timer flip-flop TFF1 is inverted.
