Implementation Notes

The failure (Failure = 0) is tested. In manual mode (PCMode = 0), the switch in the stop position clears the failure. In PC master software mode (PCMode = 1), the failure is cleared by ClearFail flag or the switch in the stop position. If start condition is valid Strt_F is set, Stop_F is cleared, and the next state entered.

See Figure 5-13.
