Timer Operating Modes
The timers are 16-bit up-counters. Minimum time-out delay is set by loading the value
0001H
to 1. Maximum time-out delay is set by loading the value
High and Low Byte registers and setting the prescale value to 128. If the Timer reaches
FFFFH
The timers can be 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. Upon 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.
Also, if the Timer Output alternate function is enabled, the Timer Output pin changes state
for one system clock cycle (from Low to High or from High to Low) upon timer Reload. If
