When the SPI is enabled, the data direction of the MOSI, MISO, SCK, and SS pins is overrid-

den according to Table 13-1. For more details on automatic port overrides, refer to “Alternate

Port Functions” on page 72.

Note:

1. See “Alternate Functions of Port B” on page 81 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 direc-

tion bits for these pins. E.g. if MOSI is placed on pin PB2, replace DD_MOSI with DDB2 and

DDR_SPI with DDRB.
