Note:
Note:
The SPIF bit can be cleared during a second transmission; however, it must be cleared
before the second SPIF bit in order to prevent an Overrun condition (see
condition
Clock phase and clock polarity
Four possible timing relationships may be chosen by software, using the CPOL and CPHA
bits (See
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.
Figure 77
The diagram may be interpreted as a master or slave timing diagram where the SCK pin, the
MISO pin and the MOSI pin are directly connected between the master and the slave
device.
If CPOL is changed at the communication byte boundaries, the SPI must be disabled by
resetting the SPE bit.
Figure
(OVR)).
shows an SPI transfer with the four combinations of the CPHA and CPOL bits.
