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 Reload High and Low Byte registers to set the reload value.
6. If required, enable the timer interrupt and set the timer interrupt priority by writing to
7. If using the Timer Output function, configure the associated GPIO port pin for the
8. Write to the Timer Control 1 register to enable the timer.
In COMPARATOR COUNTER mode, the number of comparator output transitions since
the timer start is given by the following equation:
PWM Single Output Mode
In PWM Single Output mode, the timer outputs a Pulse Width Modulator output 
signal through a GPIO Port pin. The Timer counts timer clocks up to the 16-bit Reload
value. The timer first counts up to the 16-bit PWM match value stored in the Timer PWM0
High and Low Byte registers. When the timer count value matches the PWM value, the
Timer Output toggles. The timer continues counting till it reaches the 
Reload value stored in the Timer Reload High and Low Byte registers. On reaching the
Reload value, the timer generates an interrupt, the count value in the Timer High and 
Low Byte registers is reset to
If the TPOL bit in the Timer Control 1 register is set to 1, the Timer Output signal begins
as High (1) and then transitions to Low (0) when the timer value matches the PWM value.
The Timer Output signal returns to High (1) after the timer reaches the Reload value and is
reset to
If the TPOL bit in the Timer Control 1 register is set to 0, the Timer Output signal begins
as Low (0) and then transitions to High (1) when the timer value matches the PWM value.
The Timer Output signal returns to Low (0) after the timer reaches the Reload value and is
reset to
TICONFIG.
This only affects the first pass in COMPARATOR COUNTER mode. After the first
timer Reload in COMPARATOR COUNTER mode, counting always begins at the
