Figure 85. Data Transmission Format (CPHA = 0)
Figure 86. Data Transmission Format (CPHA = 1)
As shown in Figure 85, the first SCK edge is the MSB capture strobe. Therefore the
Slave must begin driving its data before the first SCK edge, and a falling edge on the SS
pin is used to start the transmission. The SS pin must be toggled high and then low
between each byte transmitted (Figure 87).
Figure 87. CPHA/SS Timing
Figure 86 shows an SPI transmission in which CPHA is “1”. In this case, the Master
begins driving its MOSI pin on the first SCK edge. Therefore, the Slave uses the first
SCK edge as a start transmission signal. The SS pin can remain low between transmis-
