How can we disable the internal pull-up resistor on a SCT input pin LPC4367

Hello,

 

We are currently struggling to disable the internal pull-up resistor on a SCT input pin.

We are using the OM13084 board and the pin we are using is:

Header: J1.19

Pin: P2_6

Function: T3_CAP3

 

Where can we set the mode of this pin?

According to UM10503 page 258, the reset state of this pin can either be Neutral or with a pull-up.

 

Kind regards,

Martin

Hello,

I found the following information, unfortunately, during the reset state the pull-up can not be disabled, but at the moment the MCU is stable you can disable it with the next register.
