52840 port pin P1.00 can not use as the uart pin.

[sdssds]

Hi, my sdk version is 17.0.2, softdevice is s140, when i use the port pin P1.00 as the RX pin of the uart, it will show data bus error, i have tried use other pin as the RX, it can be inited and work well. Do i need to do some settings to let this pin work?

Hi

Can you show me how you are setting the P1.00 pin as an RX pin in your project? Have you set the Port to 1 correctly, so taht it doesn't use the P0.00 pin which is already used by the external LF crystal.

Best regards,

Simon
