14.6 Low Voltage Detector characteristics

CILCR:LVL[3:0] are the low voltage detector level select bits of the CILCR register.

For correct detection, the slope of the voltage level must satisfy

Faster variations are regarded as noise and may not be detected.

The functional operation of the MCU is guaranteed down to the minimum low voltage detection level of “Level 0” (VDL0_MIN).

The electrical characteristics however are only valid in the specified range (usually down to 3.0V).

(TA = -40 °C to +125 °C, Vcc = AVcc = 3.0V - 5.5V, Vss = AVss = 0V)
