Data Bus
The SPI module is a synchronous serial interface use-
ful for communicating with external peripherals and
other
devices may be Serial EEPROMs, shift registers, dis-
play drivers, Analog-to-Digital Converters, etc. The
PIC32MX SPI module is compatible with Motorola
and SIOP interfaces.
Following are some of the key features of this module:
• Master and Slave Modes Support
• Four Different Clock Formats
• Framed SPI Protocol Support
• User Configurable 8-bit, 16-bit and 32-bit Data
• Separate SPI Data Registers 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
