Family Reference ManualDS61106G-page 23-2 2007-2011 Microchip Technology INTRODUCTIONThe Serial Peripheral Interface (SPI) module is a synchronous Serial Interface useful for communicating with external peripherals and other microcontroller devices. These Peripheral devices may be a Serial EEPROM, shift register, display driver, Analog-to-Digital Converter(ADC), or an audio codec. The PIC32 family SPI module is compatible with Motorola SPI and SIOP interfaces. Figure 23-1 shows a block diagram of the SPI of the key features of this module are: Master and Slave modes support Four different clock formats Framed SPI protocol support Standard and Enhanced Buffering modes (Enhanced buffering mode is not available on all devices) User-configurable 8-bit, 16-bit, and 32-bit data width SPI receive and transmit buffers are FIFO buffers, which are 4/8/16 deep in Enhanced Buffering mode Programmable interrupt event on every 8-bit, 16-bit, and 32-bit data transfer Audio Protocol Interface modeSome PIC32 devices support audio codec Serial protocols such as Inter-IC Sound ()
