Communication Mode Parallel Suitable for short distance communication, the parallel communication control is simple and the relative transmission speed is fast (8 bits are transmitted together). Serial Can only be transmitted by one person. Sync (Understanding) Establish the direct control of the receiver clock by the sender clock, so that the two sides achieve full synchronization. At this point, the distance between the bits of the transmitt
