What is an clock data validation?
Real Time ClockFunction
These RTCs provide a power-on reset function, an oscillation halt sensing function and a supply voltage monitoring function.
These functions can be applied to judge a clock data validity.
- Power-on Reset Function
Power-on reset circuit is configured to reset a control register and store the status as a flag after initial power on from 0 V without backup battery. - Oscillation Halt Sensing Function
Oscillation halt sensing circuit is equipped with internal registers configured to record any past oscillation halt as a flag. - Supply Voltage Monitoring Function
Supply voltage monitoring circuit is configured to record a drop in supply voltage below supply voltage monitoring thresholds.
