Simple two-wire communication protocol with feedback status

摘要

A two-wire communication protocol between a controller device and a controlled device, wherein both devices are coupled by a clock line and a data line. The controller device sends control signals comprising N bits, N being greater than or equal to two, to the controlled device via the data line. Each bit of said control signals is latched onto the controlled device on consecutive edges of a clock signal sent by the controller device to the controlled device on the clock line.
