Figure 52 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 (PMRC1) of port mode register C (PMRC:
$025) to 0 or 1. The output level control example is shown in figure 53. Note that the output level cannot be
controlled in transfer state.
