The Serial Peripheral Interface (SPI) allows high-speed synchronous data transfer between the
ATmega164P/324P/644P and peripheral devices or between several AVR devices.
USART can also be used in Master SPI mode, see “USART in SPI Mode” on page 198.
The Power Reduction SPI bit, PRSPI, in
50 must be written to zero to enable SPI module.
