The Voltage Level Detector monitors the state of the system battery. It returns a logical high
value (an interrupt) in the status register if the supplied voltage drops below the user defined
level.
Voltage level detector operation
1) Absolute precision of the threshold voltage is ±10%.
2) This timing is respected in case the internal RC or crystal oscillators are selected. Refer to the clock
block documentation in case the external clock is used.
Minimum pulse width detected
Can be switched off, on or simultaneously with CPU activities
Generates an interrupt if power supply is below a pre-determined level
