ATmega165/V

2573G–AVR–07/09

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.

Note:

1. See “Alternate Functions of Port B” on page 62 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. E.g. if MOSI is placed

on pin PB5, replace DD_MOSI with DDB5 and DDR_SPI with DDRB.
