ADC ISR not triggering the exit from HAL_EnterSleepMode.

[MrAzn69]

I was under the impression the adc handler would by default generate a flag to exit the sleep mode. The interrupt never flags the exit. I know there is a parameter inside HAL_EnterSleepMode that will exit if there is a interrupt but it doesnt seem to trigger.  Can someone provide insight or a simple example of how I would flag the exit of sleep mode properly w/o timer.
