Increasing the core level when SVS/SVM low side is configured in full-performance mode causes device reset
When the SVS/SVM low side is configured in full performance mode (SVSMLCTL.SVSLFP = 1), the setting time delay for the SVS comparators is ~2us. When increasing the core level in full-performance mode; the core voltage does not settle to the new level before the settling time delay of the SVS/SVM comparator expires. This results in a device reset.
When increasing the core level; enable the SVS/SVM low side in normal mode (SVSMLCTL.SVSLFP=0). This provides a settling time delay of approximately 150us allowing the core sufficient time to increase to the expected voltage before the delay expires.
