quoted "If the CPU is powered down, the watchdog is disabled if WDCLK = 0 "
You reply
"I aggree with you, but if the device is being used to generate an interrrupt"
Sure it can, if you use PCLK which stop during idle you get no interrupts.

=============================================
Erik I am missunderstanding you here. You are saying I could use the WDT to generate an interrupt and if I choose the PCLK as the oscillator for the wdt then I get no interrupt if the device enter any power down?
===================================================
If I miss it can you rephrase what you wrote above. Remember the device is in idle 24/7 and its giving an interrupt when it enters it. Using wdt oscillator.

Thanks!
