18.0
The Serial Peripheral Interface (SPI) module is a syn-
chronous serial interface useful for communicating with
other peripheral or microcontroller devices. These
peripheral devices may be serial EEPROMs, shift regis-
ters, display drivers, ADC, etc. The SPI module is
compatible with SPI and SIOP from Motorola

Each SPI module consists of a 16-bit shift register,
SPIxSR (where x = 1 or 2), used for shifting data in and
out, and a buffer register, SPIxBUF. A control register,
SPIxCON, configures the module. Additionally, a status
register, SPIxSTAT, indicates various status conditions.
The serial interface consists of 4 pins: SDIx (serial data
input), SDOx (serial data output), SCKx (shift clock input
or output) and SSx (active-low slave select).
In Master mode operation, SCK is a clock output, but in
Slave mode, it is a clock input.

In this section, the SPI modules are
referred to together as SPIx, or separately
as SPI1 and SPI2. Special Function Reg-
isters will follow a similar notation. For
example, SPIxCON refers to the control
register for the SPI1 or SPI2 module.
