Transfer Format PHASE Equals Zero
Figure 24
The two SCK waveforms show polarity with CLKPOL reset to 0 and with CLKPOL set to
one. The diagram may 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.
Transfer Format PHASE Equals One
