Follow the steps below for configuring a timer for PWM Single Output mode and
initiating the PWM operation:
1. Write to the Timer Control 1 register to:
2. Write to the Timer Control 2 register to choose the timer clock source.
3. Write to the Timer Control 0 register to set the timer interrupt configuration field
4. Write to the Timer High and Low Byte registers to set the starting count value
5. Write to the Timer PWM0 High and Low Byte registers to set the PWM value.
6. Write to the Timer Reload High and Low Byte registers to set the Reload value (PWM
7. If desired, enable the timer interrupt and set the timer interrupt priority by writing to
8. Configure the associated GPIO port pin for the Timer Output alternate function.
9. Write to the Timer Control 1 register to enable the timer and initiate counting.
The PWM period is given by the following equation:
If an initial starting value other than
registers, the ONE-SHOT mode equation must be used to determine the first PWM 
timeout period.
If TPOL is set to 0, the ratio of the PWM output High time to the total period is given by:
If TPOL is set to 1, the ratio of the PWM output High time to the total period is given by:
