Note:  
1. See “Port B Pins Alternate Functions” on page 58 for a detailed description of how to define  
the direction of the user defined SPI pins.  
The following code examples show how to initialize the SPI as a Master and how to perform a  
simple transmission. DDR_SPI in the examples must be replaced by the actual Data Direction  
Register controlling the SPI pins. DD_MOSI, DD_MISO and DD_SCK must be replaced by the  
actual data direction bits for these pins. E.g. if MOSI is placed on pin PB5, replace DD_MOSI  
with DDB5 and DDR_SPI with DDRB.
