ADC self-test

[vonh2]

Hi, for the ADC module, does YTM32B1LE0 has any build-in seft-test?
I acknowledged the analog watchdog to monitor the ADC range but it not my case where I want to check if the ADC conversion is correct. My intention is that I can connect an DAC output pin to an ADC input pin to read the conversion result and compare with the configured DAC output to verify the ADC correctness. However, I have to modify my hardware PCB design. So is there any method, build-in feature to fulfill this self-test or if the MCU has any others mechanism to do the ADC self-test please let me know.

Thank you

As shown in the figure
You can choose the internal channel as the ADC module self-test

Thanks for the information,
However, in my YTM32B1LE0x Reference Manual (revision 1.7), there is no information about the PCU memory map. Could you tell me which document contain the shared picture?

Thank you

This register has not been developed for customers. If there is a high requirement for functional safety, self checking can be achieved through this register.

Hi, do you have any plan to introduce this feature in your next revision of the YTM32B1LE0x Reference Manual? if yes may I know when? Thank you

Hello, could you share me some information regarding the above information? Thank you

Hello ，Currently, there are no plans to update this ADC self-test information.

Hello, since we need to configure PCU register to connect VDD15 to ADC CH23, do we need to configure PCU register to connect VSS15 to ADC CH22?Thank you
