Hi.

 

I am looking at the KM series' reference manual.
The following explanation is given in "11.6.1 Pin control".
"Note that the internal pull resistor is automatically disabled whenever the output buffer is enabled for the Pull Enable bit to remain set."

(1) Does the GPIO output port indicate that the built-in pull resistance can not be set or used?
(2) Is it pull enable, but is the output port pull resistance not allowed?
(3) In which case should you use the above? (The register is a pull permission, but there is no pull resistance.)

 

I hope you will.
