Timer Operating Modes
The timers are configured to operate in the following modes:
ONE-SHOT Mode
In ONE-SHOT mode, the timer counts up to the 16-bit reload value stored in the Timer
Reload High and Low byte registers. The timer input is the system clock. When the timer
reaches the reload value, it generates an interrupt and the count value in the Timer High
and Low byte registers is reset to
counting.
If the timer output alternate function is enabled, the timer output pin changes state for one
system clock cycle (from Low to High then back to Low if TPOL = 0) at timer Reload. If
the timer output is required to make a permanent state change on ONE-SHOT timeout,
first set the TPOL bit in the Timer Control 1 Register to the start value before beginning
ONE-SHOT mode. Then, after starting the timer, set TPOL to the opposite value.
Observe the following steps to configure a timer for ONE-SHOT mode and initiate the
count.
1. Write to the timer control registers 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. Enable the timer interrupt, if required and set the timer interrupt priority by writing to
5. When 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 and initiate counting.
