Note:
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. If appropriate, enable the timer interrupt and set the timer interrupt priority by writing
5. If using the Timer Output function, configure the associated GPIO port pin for the
6. Write to the Timer Control 1 register to enable the timer. Counting does not start until
The timer period is calculated by the following equation (Start Value = 1):
The one-shot delay from input trigger to output includes the above-defined timeout period,
plus an additional delay of 2–3 system clock cycles, due to the synchronization of the input
trigger.
CONTINUOUS Mode
In CONTINUOUS mode, the timer counts up to the 16-bit reload value stored in the Timer
Reload High and Low Byte registers. After reaching the reload value, the timer generates
an interrupt, the count value in the Timer High and Low Byte registers is reset to
and counting resumes. Also, if the Timer Output alternate function is enabled, the Timer
Output pin changes state (from Low to High or High to Low) after timer reload.
Follow the steps below to configure a timer for CONTINUOUS mode and initiate the
