The edge of SCK is selected by programming bit CES. The waveform shown in Fig.13
is applicable regardless of whether the EM78451 is under master or slave mode with
/SS disabled. However, The waveform in Fig. 14 can only be implemented in slave
mode with /SS enabled.
1 = Receive is completed, SPIB is full.
0 = Receive is ongoing, SPIB is empty.
