DSA 通讯协议（EN）
DSA通讯协议最初应用于CD、DVD伺服解码芯片与外挂主控MCU之间进行数据传递，它只需要采用3个普通的IO口作为通讯端口,就可以很方便的实现双向串行数据传输。该协议越来越广泛的用于两个MCU之间的数据传递。,DSA communication protocol (EN) DSA communication protocol used in the original CD, DVD decoder chip and plug servo control data transfer between the MCU, it only needed three common IO port as a communications port, you can easily achieve the two-way serial data transmission. The agreement for two more and a wide range of data transfer between the MCU.
