Input Sample Time
(CLKPOL = 0)
(CLKPOL = 1)
Transfer Format PHASE Equals Zero
Figure 77 illustrates the timing diagram for an SPI transfer in which PHASE is cleared to
0. 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 since
the SCK Master-In/Slave-Out (MISO) and Master-Out/Slave-In (MOSI) pins are directly
connected between the Master and the Slave.
Figure 77. SPI Timing When
Transfer Format PHASE Equals One
Figure 78 illustrates the timing diagram for an SPI transfer in which PHASE is one. Two
waveforms are depicted for SCK, one for CLKPOL reset to 0 and another for CLKPOL set
to 1.
