Figure 67 Serial Interface State Transitions
Output Level Control in Idle States:
In idle states, that is, STS wait state and transmit clock wait state,
the output level of the SO pin can be controlled by setting bit 1 (SMRB1) of serial mode register B (SMRB:
$028) to 0 or 1. The output level control example is shown in figure 68. Note that the output level cannot
be controlled in transfer state.
