Features
Overview
The Serial Peripheral Interface (SPI) allows high-speed synchronous data transfer between the
ATmega48A/48PA/88A/88PA/168A/168PA/328/328P and peripheral devices or between sev-
eral AVR devices.
The USART can also be used in Master SPI mode, see “USART in SPI Mode” on page 205. The
