unexpected interrupt after power down

Question asked by Florian Rötzer on Nov 24, 2016

Hello,

 

we use the CLRC663.

Description of the problem:

   1. we use the power down for approx. 2s

   2. after that there appears no interrupt on IRQ

   --> ok

   ______________________________________

   1. we use the power down for approx. 20s

   2. after that there appears an interrupt on IRQ (100ms), without any action which could Trigger the Interrupt

   --> failure

 

Why does this Interrupt appear after a "long time" ?

 

Best regards

Florian
