Sunplus MCU simulate SPI bus function

EM推出的可读写卡片EM4469，带有512bit存储空间，程序基于AVR系列单片机，可对EM4469进行读定操作-EM introduced the card can read and write EM4469, with 512bit memory space, the program series based on the AVR microcontroller, can be read on the EM4469 is scheduled to operate

单片机最小系统，两位LED数码管由串口输出接两个164驱动，Lout,Rout为左右声道输出，SET， ALT0， ALT1为三个按键，也可自己在开始的I/O定义改成你想用的I/O口；12M晶振若用89C51则只可装下约14首歌曲，用89C52则可装下近40曲-smallest SCM system, two LED digital serial output from the pipe then two 164-driven, Lout, Rout for about channel output, SET, ALT0, ALT1 to three keys, but also his own in the beginning I/O definition you want to change the I/O port; If using crystal 12M 89C51 can carry only about 14 songs, can be loaded with 89C52 Near 40
