Ah, that is no problem at all. I am happy you were able to identify the issue! :)
For future reference, it would be beneficial if you share your code, so we may get the complete picture of what modules are being involved.

Best regards,

Hi David,

Have you seen the Pin register values, and their configuration following resets?
The register value following reset is written at the top of each register description.

It is hard to pinpoint without having seen your code, but the current draw you describe matches that of an enabled pullup resistor.
Could you ensure that you are not leaving a pullup resistor enabled anywhere?

Let me know if this identifies your extra current draw, and get back to me if it does not.
In the case that it does not, please share the code that you are running, so I may take a look.

Best regards,
Karl

I figured out that it is the RTC clock draws the extra current.

Case closed. Sorry for the confusion.

Thank you,

David
