If the timer output alternate function is enabled, the timer output pin changes state (from
Low to High or High to Low) at timer Reload. The initial value is determined by the
TPOL bit.
CAPTURE Mode
When the timer is enabled in CAPTURE mode, it counts continuously and resets to
from
stored in the PWM high and low byte registers, an interrupt is generated and the timer
continues counting. The timer continues counting up to the 16-bit Reload value stored in
the timer reload high and low byte registers. On reaching the Reload value, the timer
generates an interrupt and continues counting.
CAPTURE RESTART Mode
When the timer is enabled in CAPTURE RESTART mode, it counts continuously until
the capture event occurs or the timer count reaches the 16-bit Compare value stored in the
timer reload high and low byte registers. If the Capture event occurs first, the timer
counter value is captured and stored in the PWM High and Low byte registers, an interrupt
is generated and the count value in the timer high and low byte registers is Reset to
and counting resumes. If no Capture event occurs, on reaching the Reload value, the timer
generates an interrupt, the count value in the timer high and low byte registers is Reset to
0001H
CAPTURE/COMPARE Mode
The CAPTURE/COMPARE mode is identical to CAPTURE RESTART mode except that
counting does not start until the first appropriate external timer reload high and low byte
Input transition occurs. Every subsequent appropriate transition (after the first) of the
timer reload high and low byte Input signal captures the current count value. When the
Capture event occurs, an interrupt is generated, the count value in the Timer Reload High
and Low byte High and Low Byte registers is reset to
Capture event occurs, on reaching the Compare value, the timer generates an interrupt, the
count value in the timer high and low byte registers is Reset to
resumes.
Follow the steps below to configure a timer for one of the CAPTURE modes and initiate
the count:

Disable the timer.
Configure the timer for the selected CAPTURE mode.
Set the prescale value.
Set the Capture edge (rising or falling) for the timer input.
