ATtiny87/ATtiny167
When the SPI is enabled, the data direction of the MOSI, MISO, SCK, and SS pins is overrid-
den according to
Port Functions” on page
Table 13-1.
Note:
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.
