同步串行数据发送电路SSDT的基本功能是将并行数据转换成串行数据并进行同步发送。系统写入和读出时序完全兼容Intel8086时序。 系统以同步信号开始连续发送四个字节，在发送中出现5个1时插入一个0，在四个数据发送结束而下一次同步没有开始之前，发送7FH，这时中间不需要插入零 -synchronous serial data transmission circuit SSDT the basic function is to convert parallel data into serial and the same this step. System write and read sequential fully compatible Intel8086 timing. Synchronized signal system to start sending four consecutive bytes, in this emerging 5 1:00 insert a 0, at the end of four data sent and the next synchronization not started before, sending seven FH, then the middle is not inserted
