Timer
There are eleven 16-bit timers. These timers can be classified by function into timers A (five) and timers B
(six). All these timers function independently. Figures 1.13.1 and 1.13.2 show the block diagram of timers.

Note 1: The TA0IN pin (P71) is shared with RxD2, SCL and the TB5IN pin, so be careful.
Note 2: Timer A1 and A2 have no pin to perform input/output. Thus I/O functions like as external event input, PWM output
and one-shot output cannot be used.
