2. Write to the Timer High and Low Byte registers to set the starting count value. This
3. Write to the Timer Reload High and Low Byte registers to set the Reload value.
4. If desired, enable the timer interrupt and set the timer interrupt priority by writing to
5. Configure the associated GPIO port pin for the Timer Input alternate function.
6. Write to the Timer Control 1 register to enable the timer.
7. Assert the Timer Input signal to initiate the counting.
CAPTURE/COMPARE Mode
In CAPTURE/COMPARE mode, the timer begins counting on the first external Timer
Input transition. The desired transition (rising edge or falling edge) is set by the TPOL bit
in the Timer Control 1 Register. The timer input is the system clock.
Every subsequent desired transition (after the first) of the Timer Input signal captures the
current count value. The Capture value is written to the Timer PWM High and Low Byte
Registers. When the Capture event occurs, an interrupt is generated, the count value in the
Timer High and Low Byte registers is reset to
If no Capture event occurs, the timer counts up to the 16-bit Compare value stored in the
Timer Reload High and Low Byte registers. Upon reaching the Compare value, the timer
generates an interrupt, the count value in the Timer High and Low Byte registers is reset to
0001H and counting resumes.
Follow the steps below for configuring a timer for CAPTURE/COMPARE mode and initi-
ating the count:
1. Write to the Timer Control 1 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 Compare value.
4. If desired, enable the timer interrupt and set the timer interrupt priority by writing to
5. Configure the associated GPIO port pin for the Timer Input alternate function.
