Introduction
This section describes the serial peripheral interface (SPI) module,
which allows full-duplex, synchronous, serial communications with
peripheral devices.
Features
Features of the SPI module include:
• 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
• Serial Clock with Programmable Polarity and Phase
• Two Separately Enabled Interrupts with CPU Service:
– SPRF (SPI Receiver Full)
– SPTE (SPI Transmitter Empty)
• Mode Fault Error Flag with CPU Interrupt Capability
• Overflow Error Flag with CPU Interrupt Capability
• Programmable Wired-OR Mode
• I²C (Inter-Integrated Circuit) Compatibility
