SAM3N00B micro repeatedly powers up and down.

Sat Apr 27, 2013 2:59 pm

Hello,

We are using a SAM3N00B microcontroller in our "special" emergency light application.

Whenever the battery is removed when the mains is ON, the microcontroller repeatedly powers down and powers back up again.......(once every 5 seconds)

Is this a problem? (does repeated power up and down damage the micro?)

Our new software engineer says it is a problem, but can't say why.
Its certainly not a problem from the point of view of the operation of the unit.
