Is it possible to use a 1k external pull up in parallel to the internal 9K5?

Hi Bernd,

Thanks for the query. Ill bring this up to the team for discussion. Should have an update by Monday at the latest.

Hi Bernd,

After talking to the team, we have the following thoughts on this. It depends on what the function of the pin is. If it is used as an interrupt, then the recommendation would be to put 2.2k PU on the pin. If it is a power down function, then it does not matter the resistor value.

Sincerely,

Gerome
