Internal Voltage Comparator
Preliminary User’s Manual U14913EE1V0UM00
The comparator threshold and hysteresis are set by three external resistors:
Figure 19-2: Internal Voltage Comparator
The threshold has to be set to a voltage above 4.5 V to guarantee the frequency change within the time
the supply voltage drops below 4.5 V. The minimum threshold therefore depends on the maximal speed
the supply voltage drops down and it depends on the execution time of the interrupt service routine.
