Serial Peripheral Interface Module (SPI)
10.1 Introduction
This section describes the serial peripheral interface (SPI) module, which allows full-duplex,
synchronous, serial communications with peripheral devices.
10.2 Features
Features of the SPI module include the following:
10.3 Pin Name Conventions and I/O Register Addresses
The text that follows describes the SPI. The SPI I/O pin names are SS (slave select), SPSCK (SPI serial
clock), CGND (clock ground), MOSI (master out slave in), and MISO (master in/slave out). The SPI
shares four I/O pins with four parallel I/O ports.
The full names of the SPI I/O pins are shown in
follows.

Full-duplex operation
Master and slave modes
Double-buffered operation with separate transmit and receive registers
Four master mode frequencies (maximum = bus frequency ÷ 2)
Maximum slave mode frequency = bus frequency
Serial clock with programmable polarity and phase
Two separately enabled interrupts:
–

Mode fault error flag with CPU interrupt capability
Overflow error flag with CPU interrupt capability
Programmable wired-OR mode
