Note: Timer2 will increase in proper condition while it is enable, it overflows when TMR2CNT = TMR2PR,
TMR2CNT will be clear to 0x0000 when overflow, and the interrupt flag will be set „1‟ by hardware.

The overflow period of the timer is: Tinc-source * T2PSR * (T2PR + 1).

Note: TMR2PWM is reserved in timer/counter mode. In PWM mode, it is used as duty cycle setting. In capture
mode, the value of TMR2CNT will be captured to TMR2PWM when selected event occurs.
