SPI modes

These devices can be driven by a microcontroller with its SPI peripheral running in either of

the following two modes:

• CPOL=0, CPHA=0

• CPOL=1, CPHA=1

For these two modes, input data is latched in on the rising edge of Serial Clock (C), and

output data is available from the falling edge of Serial Clock (C).

The difference between the two modes, as shown in Figure 6, is the clock polarity when the

bus master is in Stand-by mode and not transferring data:

• C remains at 0 for (CPOL=0, CPHA=0)

• C remains at 1 for (CPOL=1, CPHA=1)
