Please let me know that what is the purpose of Fail Safe Clock Monitor and Brown-out Detection

and in which event we need to use them?
 

Hi,

This app note explains Fail Safe https://ww1.microchip.com/downloads/en/AppNotes/00892a.pdf


This is the relevant bit of a good thread https://www.microchip.com/forums/m672837.aspx

All that Brown Out Reset does is automatically put the processor in reset if the power coming into the chip isn't sufficient to work reliably. Essentially, if lack of power is going to cause funky behavior, the processor will hold in reset rather than try and keep running. It should then resume once the voltage has gone above the brownout threshold
