Data Modes
As the SS pin is used to signal start and end of transfer, it is also useful for doing packet/byte
synchronization, keeping the Slave bit counter synchronous with the Master clock generator.
There are four combinations of SCK phase and polarity with respect to serial data. The SPI data
transfer formats are shown in
edges of the SCK signal, ensuring sufficient time for data signals to stabilize.
Table 20-2.
Leading edge is the first clock edge in a clock cycle. Trailing edge is the last clock edge in a
clock cycle.
