15.1. Normal Mode
The MCU is fully functional in normal mode. Figure 15.1 shows the on-chip power distribution to various
peripherals. There are two supply voltages powering various sections of the chip: V
nal core supply. All analog peripherals are directly powered from the V
CIP-51 core are powered from the 1.8 V internal core supply. RAM, PMU0 and the SmaRTClock are
always powered directly from the VBAT pin in sleep mode and powered from the core supply in all other
power modes.
