Note:
1. See “Alternate Functions Of Port B” on page 67 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 per-
form 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. For example, if MOSI is
placed on pin PB5, replace DD_MOSI with DDB5 and DDR_SPI with DDRB.
