14.1. Normal Mode
The MCU is fully functional in Normal Mode. Figure 14.1 shows the on-chip power distribution to various
peripherals. There are three supply voltages powering various sections of the chip: VBAT, VDD/DC+, and
the 1.8 V internal core supply. VREG0, PMU0 and the SmaRTClock are always powered directly from the
VBAT pin. All analog peripherals are directly powered from the VDD/DC+ pin, which is an output in one-cell
mode and an input in two-cell mode. All digital peripherals and the CIP-51 core are powered from the 1.8 V
internal core supply. The RAM is also powered from the core supply in Normal mode.
