Sequence for Method 3:
1. Select the automatic write of duty-cycle values and automatically update by setting the
2. Define the synchronous channels by the SYNCx bits in the SCM register.
3. Define the update period by the UPR field in the SCUP register.
4. Define when the WRDY bit and the corresponding PDCA transfer request must be set
5. Define the PDCA transfer settings for the duty-cycle values and enable it in the PDCA
6. Enable the synchronous channels by writing CHID0 in the ENA register.
7. If an update of the period value and/or of the dead-time values is required, write regis-
