摘要
在数字终端中，语音编解码器与微处理器的接口是重要一环。介绍通过移位寄存器将语音编解码器（ＣＯＤＥＣ）ＭＣ１４５５０３与微处理器连接，实现语音的录入、存储、处理及播放功能，用于特种电话服务、数字终端及通信，具有实用意义。
In
digital terminal,the interface between CODEC (voice coder and decoder) and mi croprocessor is an
essential link. Through shift registers the MC145503 CODEC is linked with microprocessor,and
functions of recording,storing,processing and pla ying of voice information can be
implemented.It's practical to be used in specia l telephone service,digital terminal and
communication.
