Data Modes
ATtiny87/ATtiny167
There are four combinations of SCK phase and polarity with respect to serial data, which are
determined by control bits CPHA and CPOL. The SPI data transfer formats are shown in
ure 13-3
SCK signal, ensuring sufficient time for data signals to stabilize. This is clearly seen by sum-
marizing
Table 13-5.
