Features
Overview
The Serial Peripheral Interface (SPI) allows high-speed full-duplex, synchronous data transfer
between different devices. Devices can communicate using a master-slave scheme, and data is
transferred both to and from the devices simultaneously.
PORTC and PORTD each has one SPI. Notation of these peripherals are SPIC and SPID,
respectively.
Two Identical SPI peripherals
Full-duplex, Three-wire Synchronous Data Transfer
Master or Slave Operation
LSB First or MSB First Data Transfer
Seven Programmable Bit Rates
End of Transmission Interrupt Flag
Write Collision Flag Protection
Wake-up from Idle Mode
Double Speed (CK/2) Master SPI Mode
