Power Management Unit (PMU)
5.3.2
Voltage Regulator 1.5V (VDDC)
This module represents the 1.5 V voltage regulator, which provides the supply for the microcontroller core, the
digital peripherals and other internal analog 1.5 V functions (e.g. ADC2) of the chip. To further reduce the current
consumption of the MCU during Stop Mode the output voltage can be lowered to 0.9 V.
