Table 83. SPI Clock Phase and Clock Polarity Operation
Transfer Format Phase Equals Zero
Figure 25 illustrates the timing diagram for an SPI transfer in which
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 con-
nected between the master and the slave.
