FUNCTIONAL PT2264 encodes code address data A8/D3 A11/D0 into special waveform outputs DOUT when pulled (Low State). This waveform either modulator transmission. transmitted radio frequency received demodulator receiver reshaped special waveform. PT2294 then used decode waveform corresponding output pin(s). Thus completing remote control encoding decoding function.
