Serial Communication Protocol

摘要

A serial communication protocol for daisy-chained slave devices does away with the requirement for an entire byte of dummy clocks to be cycled between a slave's input and output, instead requiring a shorter set of dummy clock cycles which improves efficiency of a serial communication system. According to a specification of a serial communications protocol, data is exchanged between master and slave devices in communication frames. Each communication frame has a command portion and a data portion, and each respective portion may comprise packages of one or more bytes.
