VDD_LOW (option C)

VDD_LOW circuit monitors VDD regulated voltage. When VDD falls below VDDUN for a

filter time TFVDD VDD_LOW output voltage is set low.

VDDUN is a reference voltage 300 mV (Typ) lower than VCC regulated voltage.

Filter time TFVDD is spike dependent as TRR1 for VCC regulator so the same

consideration applies also in this case.
