Timer Operating Modes
The timers are 16-bit up-counters. Minimum time-out delay is set by loading the value
0001H
Maximum time-out delay is set by loading the value
low byte registers and setting the prescale value to 128. If the Timer reaches
timer resets back to
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
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) on timer reload. For the
