The Serial Peripheral Interface (SPI) module is a
synchronous serial interface useful for communicating
with other peripheral or microcontroller devices. These
peripheral devices can be serial EEPROMs, shift regis-
ters, display drivers, Analog-to-Digital Converters, 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 status conditions.
The serial interface consists of four pins:
• SDIx (serial data input)
• SDOx (serial data output)
• SCKx (shift clock input or output)
• SSx (active-low slave select).
In Master mode operation, SCKx is a clock output. In
Slave mode, it is a clock input.
