to 0. The two SCK waveforms show polarity with CLKPOL reset to 0 and with CLKPOL
set to one. The diagram can be interpreted as either a Master or Slave timing diagram since
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 is 1
