Mode
If it is 0, the counter/timers are in the transmit mode; otherwise, they are in the
demodulation mode.
P36_Out/Demodulator_Input
In transmit mode, this bit defines whether P36 is used as a normal output pin or
the combined output of T8 and T16.
In demodulation mode, this bit defines whether the input signal to the counter/tim-
ers is from P20 or P31.
