Timer Input/Output Polarity
TPOL
This bit is a function of the current operating mode of the timer. It determines the
polarity of the input and/or output signal. When the timer is disabled, the Timer
Output signal is set to the value of this bit.
ONE-SHOT mode–If the timer is enabled the Timer Output signal pulses
(changes state) for one system clock cycle after timer Reload.
CONTINUOUS mode–If the timer is enabled the Timer Output signal is
complemented after timer Reload.
COUNTER mode–If the timer is enabled the Timer Output signal is
complemented after timer reload.
0 = Count occurs on the rising edge of the Timer Input signal.
1 = Count occurs on the falling edge of the Timer Input signal.
PWM SINGLE OUTPUT mode–When enabled, the Timer Output is forced to
TPOL after PWM count match and forced back to TPOL after Reload.
CAPTURE mode–If the timer is enabled the Timer Output signal is
complemented after timer Reload.
0 = Count is captured on the rising edge of the Timer Input signal.
1 = Count is captured on the falling edge of the Timer Input signal.
COMPARE mode–The Timer Output signal is complemented after timer
Reload.
GATED mode–The Timer Output signal is complemented after timer Reload.
0 = Timer counts when the Timer Input signal is High and interrupts are
generated on the falling edge of the Timer Input.
1 = Timer counts when the Timer Input signal is Low and interrupts are
generated on the rising edge of the Timer Input.
CAPTURE/COMPARE mode–If the timer is enabled, the Timer Output signal is
complemented after timer Reload
0 = Counting starts on the first rising edge of the Timer Input signal. The current
count is captured on subsequent rising edges of the Timer Input signal.
1 = Counting starts on the first falling edge of the Timer Input signal. The
current count is captured on subsequent falling edges of the Timer Input signal.
