红外解码程序主要工作为等待红外线信号出现，并跳过引导信号，开始收集连续32位的表面数据，存入内存的连续空间。位信号解码的原则是：以判断各个位的波宽信号来决定高低信号。位解码原理如下：  解码为0：低电平的宽度0.56ms+高电平的宽度0.56ms。  解码为1：低电平的宽度1.68ms+高电平的宽度0.56ms。 程序中必须设计一精确的0.1ms延时时间作为基础时间，以计数实际的波形宽度，若读值为5表示波形宽度为0.5ms，若读值为16表示波形宽度为1.6ms，以此类推。高电平的宽度1.12ms为固定，因此可以直接判断低电平的宽度的计数值5或时16，来确定编码为0或是1。程序中可以减法指令SUBB来完成判断，指令“SUBB A，R2”中若R2为计数值，A寄存器设为8，就可如下：  当“8－R2”有产生借位，借位标志C=1，表示编码为1。  当“8－R2”无产生借位，借位标志C=0，表示编码为0。 将借位标志C经过右移指令“RRC A”转入A寄存器中，再经由R0寄存器间接寻址存入内存中。 -err
