•
•
The Serial Peripheral Interface (SPI) allows high-speed synchronous data transfer between the
ATmega164A/164PA/324A/324PA/644A/644PA/1284/1284P and peripheral devices or between
several AVR devices.
USART can also be used in Master SPI mode, see
The Power Reduction SPI bit, PRSPI, in
50 must be written to zero to enable SPI module.
164A/164PA/324A/324PA/644A/644PA/1284/1284P
Full-duplex, Three-wire Synchronous Data Transfer
Master or Slave Operation
LSB First or MSB First Data Transfer
Seven Programmable Bit Rates
