3.3.7. SPI bus (Serial Peripheral Interface)
SPI bus Information
The Serial Peripheral Interface (SPI) is a synchronous serial communication interface
specification used for short distance communication, primarily in embedded systems.
SPI devices communicate in full duplex mode using a master-slave architecture with a
single master. The master device originates the frame for reading and writing. Multiple
slave devices are supported through selection with individual slave select (SS) lines.
