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

When the remote control signal preprocessor is used, operating states are controlled and
When this pin is used for the external interrupt 3 input, set EINT in RXCR1 to other
