Output Level Control During Idle States:
The output level of the SO pin can be set during either STS
wait state or transmit clock wait state by software. During idle states, the output level is controlled by
writing to bit 1 (PMRC1) of port mode register C (PMRC: $025). An example of output level control
during idle states is shown in figure 43. During transfer state, output level control cannot be executed.
