Mode
If the result is 0, the counter/timers are in TRANSMIT mode; otherwise, they are in
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.
If the input signal is from Port 31, a capture event may also generate an IRQ2 interrupt. To
prevent generating an IRQ2, either disable the IRQ2 interrupt by clearing its IMR bit D2
or use P20 as the input.
T8/T16_Logic/Edge _Detect
In TRANSMIT Mode, this field defines how the outputs of T8 and T16 are combined
(AND, OR, NOR, NAND).
In DEMODULATION Mode, this field defines which edge must be detected by the edge
detector.
