Note: Timer1 will increase in proper condition while it is enable, it overflows when TMR1CNT = TMR1PR,
TMR1CNT will be cleared to 0x0000 when overflow, and the interrupt flag will be set „1‟ by hardware.

The overflow period of the timer is: Tinc-source * T1PSR * (T1PR + 1).

Note: TMR1PWM is reserved in timer/counter mode. In PWM mode, it is used as duty cycle setting. In capture
mode, the value of TMR1CNT will be captured to TMR1PWM when selected event occurs.
7.3 Timer2
Timer2 is a 16-bit timer/counter with a 7-bit prescaler. It can be configured as timer, counter or PWM generator. X
