Out of range channel written in ADC seq register for STM32L475

[Harish1]

Hi,

What happens if I write them out of range channel numbers in the ADC sequence register.

For STM32L475, the channel range is 0 -18 but I wrote the channel number 19. While debugging, from debug window I found that the seq. register accepting number 19th.

But I am not getting what would happen if I do like this?

Can anybody help here?

The RM doesn't guarantee anything in this case. Using invalid settings leads to undefined behavior.
