Table 83. SPI Clock Phase and Clock Polarity Operation
Transfer Format Phase Equals Zero
Figure 25
The two SCK waveforms show polarity with CLKPOL reset to 0 and with CLKPOL set to
1. The diagram can be interpreted as either a master or slave timing diagram because the
SCK Master-In/Slave-Out (MISO) and Master-Out/Slave-In (MOSI) pins are directly
connected between the master and the slave.
