SERIAL PERIPHERAL INTERFACE (cont’d)
11.4.4 Clock Phase and Clock Polarity
Four possible timing relationships may be chosen
by software, using the CPOL and CPHA bits (See
Figure
Note: The idle state of SCK must correspond to
the polarity selected in the SPICSR register (by
pulling up SCK if CPOL = 1 or pulling down SCK if
CPOL = 0).
The combination of the CPOL clock polarity and
CPHA (clock phase) bits selects the data capture
clock edge.

the MOSI pin are directly connected between the
master and the slave device.
Note: If CPOL is changed at the communication
byte boundaries, the SPI must be disabled by re-
setting the SPE bit.
