Figure 34. ESPI Timing when PHASE = 0
16.3.2.2. Transfer Format When Phase Equals One
Figure 35 displays a timing diagram for an SPI type transfer in which PHASE is one. For
SPI transfers the clock only toggles during the character transfer. Two waveforms are
depicted for SCK, one for CLKPOL = 0 and another for CLKPOL = 1.
