2. Write to the Timer High and Low Byte Registers to set the starting count value
3. Write to the Timer Reload High and Low Byte Registers to set the Reload value.
4. Clear the Timer PWM High and Low Byte Registers to
5. If required, enable the timer interrupt and set the timer interrupt priority by writing to
6. Configure the associated GPIO port pin for the Timer Input alternate function.
7. Write to the Timer Control Register to enable the timer and initiate counting.
In CAPTURE mode, the elapsed time from timer start to Capture event is calculated using
the following equation:
COMPARE Mode
In COMPARE mode, the timer counts up to the 16-bit maximum Compare value stored
in the Timer Reload High and Low Byte Registers. The timer input is the system clock.
Upon reaching the Compare value, the timer generates an interrupt and counting continues
(the timer value is not reset to
enabled, the Timer Output pin changes state (from Low to High or from High to Low)
upon Compare.
If the Timer reaches
