When the SPI is enabled, the data direction of the MOSI, MISO, SCK, and SS pins is
overridden according to Table 59. For more details on automatic port overrides, refer to
“Alternate Port Functions” on page 60.
Table 59. SPI Pin Overrides
Note:
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. E.g. if MOSI is placed
on pin PB5, replace DD_MOSI with DDB5 and DDR_SPI with DDRB.
