As shown in Figure 28, 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 30).
Figure 29 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-
sions (Figure 30). This format may be preffered in systems having only one Master and
only one Slave driving the MISO data line.
