The keys SA1 ~ SA8 and diodes VD1 ~ VD13 form Octal matrix input circuit for the eight encoded input circuit of remote control transmitter circuit. Because the SM5262's pin 7 to 13 are used for the address / data common terminals, if ther are used as the data input terminals, the circuit has a total of six data input terminals, when all of them are used for data input, they can form a total of 26 = 64, i.e. 64-channel remote control transmitter.
