20. SPI – Serial Peripheral Interface
2549M–AVR–09/10
The Serial Peripheral Interface (SPI) allows high-speed synchronous data transfer between the
ATmega640/1280/1281/2560/2561 and peripheral devices or between several AVR devices.
The ATmega640/1280/1281/2560/2561 SPI includes the following features:
•
•
•
•
•
•
•
•
USART can also be used in Master SPI mode, see
The Power Reduction SPI bit, PRSPI, in
page 50 must be written to zero to enable SPI module.
Figure 20-1. SPI Block Diagram
Note:
The interconnection between Master and Slave CPUs with SPI is shown in
196. The system consists of two shift Registers, and a Master clock generator. The SPI Master
initiates the communication cycle when pulling low the Slave Select SS pin of the desired Slave.
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
