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.

Best regards,
Pavel

Dear Pavel,

Thank you, we managed to disable the pull-up resistor.

Kind regards,
