The SPI module is a synchronous serial interface that
is useful for communicating with external peripherals
and other microcontroller devices. These peripheral
devices may be Serial EEPROMs, Shift registers, dis-
play drivers, A/D Converters, etc. The PIC32 SPI mod-
ule is compatible with Motorola
interfaces.
Following are some of the key features of this module:
• Master and Slave modes support
• Four different clock formats
• Enhanced Framed SPI protocol support
• User-configurable 8-bit, 16-bit and 32-bit data
• Separate SPI FIFO buffers for receive and
• Programmable interrupt event on every 8-bit,
• Operation during CPU Sleep and Idle mode
• Fast bit manipulation using CLR, SET and INV
