Timer Operating Modes
The timers can be configured to operate in the following eleven modes, each of which is
described in this section:

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. After reaching
this reload value, the timer 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
If the user chooses, the Timer Output can undergo a permanent state change upon One-
Shot time-out, as follows:
1. Set the
2. After starting the timer, set TPOL to the opposite value.
The steps for configuring a timer for ONE-SHOT mode and initiating a count are as fol-
