Notes
1. A timer must be first assigned and is then automatically activated as soon as the on-time is configured.
2. If cyclic sense is selected and the HS switches are cleared during SBC Restart Mode, then also the timer
settings (period and on-time) are cleared to avoid incorrect switch detection.
3. in case the timer are set as wake sources and cyclic sense is running, then both cyclic sense and cyclic wake
will be active at the same time.
