able to form a 16-bit timer.
the timer is started by setting TC4CR<TC4S> to 1, an INTTC4 interrupt is generated and the up-counter is
cleared. After being cleared, the up-counter continues counting. Program the lower byte and upper byte in
this order in the timer register. (Programming only the upper or lower byte should not be attempted.)

Note 1: In the timer mode, fix TCjCR<TFFj> to 0. If not fixed, the PDOj, PWMj, and PPGj pins may output a pulse.
Note 2: In the timer mode, do not change the TTREGj setting while the timer is running. Since TTREGj is not in
Note 3: j = 3, 4
In the timer mode, the up-counter counts up using the internal clock. The TimerCounter 3 and 4 are cascad-
When a match between the up-counter and the timer register (TTREG3, TTREG4) value is detected after
the shift register configuration in the timer mode, the new value programmed in TTREGj is in effect imme-
diately after programming of TTREGj. Therefore, if TTREGj is changed while the timer is running, an expec-
ted operation may not be obtained.
