A.1.3.3
The pins EXTAL, XTAL dedicated to the oscillator have a nominal 1.8 V level. They are supplied by
VDDPLL.
A.1.3.4
This pin is used for production testing only.
A.1.4
Power supply must maintain regulation within operating V
operating maximum current conditions. If positive injection current (V
the injection current may flow out of V
regulation. Ensure external V
will be the greatest risk when the MCU is not consuming power; e.g., if no system clock is present, or if
clock rate is very low which would reduce overall power consumption.
