I'm looking for a power supply filter for this mcu. In page 1789 and 1790 referred that lots of the power supply pins needs decoupling capacitor filtering. Some of those pins need an additional inductor for LC filtering. The question is:
- Why Cut-Off Frequency starts from few KHz (e.g. 10kHz) and not with value closest to Zero (0Hz)?
- Why Frequency ends at few MHz (e.g. 10MHz) and not continues beyond of that boundary?
