Deep-sleep wakeup from counter

[TJ]

Hi,

I'd like to wake up from deep-sleep  when counter's capture interrupt event occurs.  I think this interrupt source cannot wake the device from deep-sleep mode, correct me if I'm wrong.  If this is the case, is there a way (trick) to accomplish this?  

Thanks

The TCPWM based counter does not run on deep-sleep. You need to use a watchdog timer instead.

If using PDL:

If using HAL:
