waveform from which the carrier wave was eliminated by the receive circuit to P30
(INT3/RXIN) pin. When the remote control signal preprocessor/external interrupt 3 pin is also
used as the P30 port, set the P30 port output latch to “1”. When it is not used as the remote
control signal preprocessor/external interrupt 3 input pin, it can be used for normal port.
The remote control signal waveform can be determined by inputting the remote control signal
