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. On reaching the
Reload value, the timer generates an interrupt and the count value in the Timer High and
Low Byte registers is reset to
counting.
state for one system clock cycle (from Low to High or vice-versa) on timer Reload.
If it is required for the Timer Output to make a permanent state change on One-Shot
time-out, first set the TPOL bit in the Timer Control Register to the start value before
beginning ONE-SHOT mode. Then, after starting the timer, set TPOL to the opposite bit
value.
Follow the steps below for configuring a timer for ONE-SHOT mode and initiating the
count:
1. Write to the Timer Control Register to:
Also, if the Timer Output alternate function is enabled, the Timer Output pin changes
