TRANSMIT mode.
DEMODULATION mode.
P36 acts as normal I/O port output.
P36 acts as combined Timer 8/Timer 16 output.
P31 acts as the demodulator input. If IMR[2] = 1, a P31 event can also generate
an IRQ1 interrupt. To prevent this, clear IMR[2] or select P20 as input instead.
P20 acts as the demodulator input.
Output is T8 AND T16.
Output is T8 OR T16.
Output is T8 NOR T16.
Output is T8 NAND T16.
Falling edge detection.
Rising edge detection.
Falling and rising edge detection.
