Hello,
I was reading the app note AN-B-056 System Level ESD Events, which is for 68x devices, but I would like to do something similar for 580 device I have. The document outlines a circuitry that depends on a PWM pulse, so it'll work right when the device is active. But when the device goes to deep sleep, say couple of seconds, then this method might not work right? Is there a way that this method can also work when the device is in deep sleep? Since the watchdog timer is shut when the device sleeps, I am not sure which other timer I could use which will not set off a trigger to this circuit.
Thanks!

Hi vmore,
While sleeping you’re going to have to wake periodically to trigger the watchdog or disable it when you enter sleep mode. If advertising could be synchronized with the wake up to do that, making the additional power consumption minimal.
