Where can I find ADCy_AWDx_OUT ?

When ADC threshold is reached ADCy_AWDx_OUT is set and stays high as long as first conversion is between low and high threshold levels.

Where can I read this value? Is possible to configure interrupt for this transitions between low and high state at ADCy_AWDx_OUT ?

Thanks

Care to reveal which processor ?

Cheers, Hal

STM32F303

I already found that it is related only to advanced timers as TIM1 and TIM8. I would like to achieve an interrupt only once when first ADC result is outside programmed threshold. ADCy_AWDx_OUT allowed this (it become high at first conversion which is higher than threshold and then stays high), but problem is because I get more than one interrupt because of noise.

I believe you should monitor the status of AWD1, AWD2 or AWD3 flag in the ADC Interrupt & Status Register. It doesn't reset until you reset it with software.
