SPI Slave Operation
Example
2543L–AVR–08/10
The following code demonstrates how to use the USI module as a SPI Master with maximum
speed (fsck = fck/2):
The following code demonstrates how to use the USI module as a SPI Slave:
The code is size optimized using only eight instructions (+ ret). The code example assumes that
the DO is configured as output and USCK pin is configured as input in the DDR Register. The
value stored in register r16 prior to the function is called is transferred to the master device, and
