The Serial Peripheral Interface (SPI) module is a synchronous serial interface useful for
communicating with other peripheral or microcontroller devices. These peripheral devices may
be serial EEPROMs, shift registers, display drivers, A/D converters, etc. The SPI module is
compatible with Motorola’s SPI and SIOP interfaces.
Each device in the dsPIC30F SMPS and Digital Power Conversion device family offers one SPI
module, designated SPI1.
The SPI1 serial interface consists of four pins:
• SDI1: Serial Data Input
• SDO1: Serial Data Output
• SCK1: Shift Clock Input or Output
• SS1: Active-Low Slave Select or Frame Synchronization I/O Pulse
The SPI1 module can be configured to operate using 2, 3 or 4 pins. In the 3-pin mode, SS1 is
not used. In the 2-pin mode, SDO1 and SS1 are both unused.
A block diagram of the SPI1 module is shown in Figure 35-1.
Note:
SPI1RXB
bit 0
Some devices in the dsPIC30F SMPS and Digital Power Conversion device family
do not contain the SS1 pin and, therefore, do not include the Framed SPI and Slave
Select functions. Refer to the specific device data sheet for details about available
SPI pins.
