1.2.4.4
Power is supplied to the MCU NVM through VDDF . The voltage supply of nominally 2.8V is derived
from the internal voltage regulator. No static external loading of these pins is permitted.
1.2.4.5
These are the power supply and ground input pins for the analog-to-digital converters and the voltage
regulator. Internally the V
together.
1.2.4.6
V
1.2.4.7
These pins provide operating voltage and ground for the oscillator and the phased-locked loop. The voltage
supply of nominally 1.8V is derived from the internal voltage regulator. This allows the supply voltage to
the oscillator and PLL to be bypassed independently. This voltage is generated by the internal voltage
regulator. No static external loading of these pins is permitted.
