Figure 21. SPI Configured as a Master in a Single Master, Multiple Slave System
The SPI is a full-duplex, synchronous, and character-oriented channel that supports a four-
wire interface (serial clock, transmit, receive and Slave select). The SPI block consists of a
transmit/receive shift register, a Baud Rate (clock) Generator and a control unit.
