Fosc: Input clock.
Prescaler ( T1P0 and T1P1/T2P1 and T2P0 ): Options of 1:2, 1:8, 1:32, and 1:64 are defined by TMRX. It is
cleared when any type of reset occurs.
TMR1X and TMR2X (TMR1H/TWR1L and TMR2H/TMR2L ):Timer X register; TMRX is increased until
it matches with PRDX, and then is reset to 0. TMRX cannot be read.
PRDX ( PRD1 and PRD2 ): PWM period register.
When defining TMRX, refer to the related registers of its operation as shown in prescale register. It must be
noted that the PWMX bits must be disabled if their related TMRXs are employed. That is, bit 7 and bit 6 of
the PWMCON register must be set to ‘0’.

Timer programming procedures/steps
(1) Load PRDX with the TIMER period.
(2) Enable interrupt function by writing IOCF PAGE0, if required
(3) Load a desired value to PWMCON with the TMRX prescaler value and enable both TMRX and disable
PWMX.
