1. Introduction：

In some particular application, few pin count but still need chip to chip communication. This IP use one wire bi-direction (open drain) to communication. Just like UART , it is consist of one TX and one RX. User can define their own payload freedomly.

 

All devices are connecting through open-drain pull high bus. Every device can send data to others actively.
