The Serial Peripheral Interface (SPI) allows high-speed synchronous data transfer between the
Atmel ATmega16HVB/32HVB and peripheral devices or between several AVR devices.
When the SPI is not used, power consumption can be minimized by writing the PRSPI bit in
PRR0 to one. See
the PRSPI bit.
Figure 18-1. SPI block diagram
Note:
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 protection flag
Wake-up from idle mode
Double speed (CK/2) master SPI mode
