Serial Peripheral Interface
19.1
Overview
The serial peripheral interface (SPI) allows the device to exchange data between other PowerQUICC®
family chips, the MC68360, MC68302, M68HC11, and M68HC05 microcontroller families, and other
family devices. The SPI can be used to communicate with peripheral devices such as EEPROMs, real-time
clocks, A/D converters, and ISDN devices.
The SPI is a full-duplex, synchronous, character-oriented channel that supports a four-wire interface
(receive, transmit, clock, and slave select). The SPI block consists of transmitter and receiver sections, an
independent baud-rate generator, and a control unit. The transmitter and receiver sections use the same
clock, which is derived from the SPI baud rate generator in master mode or externally in slave mode.
During an SPI transfer, data is sent and received simultaneously.
The SPI receiver and transmitter are double-buffered, as shown in
Figure
19-1, giving an effective FIFO
size (latency) of 2 characters. The SPI’s MSB/LSB is shifted out first. When the SPI is disabled in the SPI
mode register (SPMODE[EN] = 0), it consumes little power.
