Timer High and Low Byte registers is reset to
bit in Timer Control 0 register is set to indicate the timer interrupt is due to an input 
capture event.
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. On reaching the Compare value, the timer
generates an interrupt, the count value in the Timer High and Low Byte registers is reset to

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 Control 2 register to choose the timer clock source.
4. Write to the Timer Control 0 register to set the timer interrupt configuration field
5. Write to the Timer Reload High and Low Byte registers to set the Compare value.
6. If required, enable the timer interrupt and set the timer-interrupt priority by writing to
7. Configure the associated GPIO port pin for the Timer Input alternate function.
8. Write to the Timer Control 1 register to enable the timer.
9. Counting begins on the first transition of the Timer Input signal. No interrupt is
