Timer Input/Output Polarity
Operation of this field is a function of the current operating modes of the timer.
ONE-SHOT Mode
When the timer is disabled, the Timer Output signal is set to the value of this bit. When the
timer is enabled, the Timer Output signal is complemented upon timer reload.
CONTINUOUS Mode
When the timer is disabled, the Timer Output signal is set to the value of this bit. When the
timer is enabled, the Timer Output signal is complemented upon timer reload.
COUNTER Mode
When the timer is disabled, the Timer Output signal is set to the value of this bit. When the
timer is enabled, the Timer Output signal is complemented upon 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
0 = Timer Output is forced Low (0) when the timer is disabled. When enabled, the Timer
Output is forced High (1) on PWM count match and forced Low (0) on Reload.
1 = Timer Output is forced High (1) when the timer is disabled. When enabled, the Timer
Output is forced Low (0) on PWM count match and forced High (1) on Reload.
CAPTURE Mode
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
When the timer is disabled, the Timer Output signal is set to the value of this bit. When the
timer is enabled, the Timer Output signal is complemented on timer reload.
GATED Mode
0 = Timer counts when the Timer Input signal is High (1) and interrupts are generated on the
falling edge of the Timer Input.
1 = Timer counts when the Timer Input signal is Low (0) and interrupts are generated on the
rising edge of the Timer Input.
CAPTURE/COMPARE Mode
0 = Counting is started 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 is started on the first falling edge of the Timer Input signal. The current count is
captured on subsequent falling edges of the Timer Input signal.
