The steps for configuring a timer for CAPTURE RESTART mode and initiating the count
are as follows:
1. Write to the Timer Control register to:
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 0000H. This allows user
5. Enable the timer interrupt, if appropriate, and set the timer interrupt priority by writing
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 can be calculated
using the following equation:
Capture Elapsed Time (s)
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
the Timer Output pin changes state (from Low to High or from High to Low) upon Com-
pare.
