to form a 16-bit timer.
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 the
Note 3: j = 3, 4
In the timer mode, the up-counter counts up using the internal clock. The TimerCounter 3 and 4 are cascadable
When a match between the up-counter and the timer register (TTREG3, TTREG4) value is detected after the
16-Bit Timer Mode (TC3 and 4)
shift register configuration in the timer mode, the new value programmed in TTREGj is in effect immediately
after programming of TTREGj. Therefore, if TTREGj is changed while the timer is running, an expected
operation may not be obtained.
