1. SMPS regulator is functional in the range 2.85 V < VDD_HV_IO < 4.5 V, but at a reduced efficiency.

2. Internal schemes must be used by the application (eg frequency ramping feature enable) to ensure that incremental

demands are made on the external power supply within the maximum value. Mbist/Lbist must be configured to avoid

exceeding the maximum value.
