TRANSMIT Mode
Submode Selection—Select normal or PING-PONG mode operation, or force T16 output.
When these bits are written to 00b (NORMAL mode) or 01b (PING-PONG mode),
T16_OUT assumes the opposite state of bit CTR1[0] until the timer begins counting.
DEMODULATION Mode
Glitch Filter—Define the maximum glitch width to be rejected by the counter/timer.
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.
DEMODULATION Mode
Rising Edge—Indicates whether a rising edge was detected on the input signal. Write 1 to
this Flag to reset it.
