Serial Peripheral Interface Module (SPI)
11.1 Introduction
This section describes the serial peripheral interface module (SPI, Version C), which allows full-duplex,
synchronous, serial communications with peripheral devices.
11.2 Features

Full-Duplex Operation
Master and Slave Modes
Double-Buffered Operation with Separate Transmit and Receive Registers
Four Master Mode Frequencies (Maximum = Bus Frequency ÷ 2)
Maximum Slave Mode Frequency = Bus Frequency
Clock Ground for Reduced Radio Frequency (RF) Interference
Serial Clock with Programmable Polarity and Phase
Two Separately Enabled Interrupts with DMA or CPU Service:
–
–
Mode Fault Error Flag with CPU Interrupt Capability
Overflow Error Flag with CPU Interrupt Capability
Programmable Wired-OR Mode
I
2
C (Inter-Integrated Circuit) Compatibility
SPRF (SPI Receiver Full)
SPTE (SPI Transmitter Empty)
References to DMA and associated functions are only valid if the MCU has
a DMA module. If the MCU has no DMA, any DMA related register bits
should be left in their reset state for expected MCU operation.
