Description
TRANSMIT Mode
Initial Timer 8 Out—Select the initial T8_OUT state when Timer 8 is enabled.
While the timer is disabled, the opposite state is asserted on the pin to ensure
that a transition occurs when the timer is enabled. Changing this bit while the
counter is enabled can cause unpredictable output on T8_OUT.
T8_OUT transitions from High to Low when Timer 8 is enabled.
T8_OUT transitions from Low to High when Timer 8 is enabled.
DEMODULATION Mode
Rising Edge—Indicates whether a rising edge was detected on the input signal.
Write 1 to this flag to reset it.
No rising edge detection.
Rising edge detection.
No effect.
Reset flag to 0.
TRANSMIT Mode
Initial Timer 16 Out—In NORMAL or PING-PONG mode, this bit selects the initial
T16_OUT state when Timer 16 is enabled. While the timer is disabled, the
opposite state is asserted on the pin to ensure that a transition occurs when the
timer is enabled. Changing this bit while the counter is enabled can cause
unpredictable output on T16_OUT.
If CTR1[3]=0, T16_OUT transitions from High to Low when Timer 16 is enabled.
If CTR1[3]=0, T16_OUT transitions from Low to High when Timer 16 is enabled.
DEMODULATION Mode
Falling Edge—Indicates whether a falling edge was detected on the input signal.
Write 1 to this flag to reset it.
No falling edge detection.
Falling edge detection.
No effect.
Reset flag to 0.
