MKL04Z16 - SWD_CLK as Output

Hello community,

i have a design with a MKL04Z16 controller and we want to use the Pin 30 (SWD_CLK in default) as GPIO Output. 

It is possible to use this as output (see screenshot)pastedImage_1.png

But is it possible after flashing the SWD_CLK as output to debug again ?

Thanks in advance.

Best regards,

Juergen

Hi Juergen,

This pin can be configured as GPIO Output.
But it's not recommended due to it will effect SWD function when you want to debug it again.
You may need to recover it by specify method: Bricking and Recovering FRDM-KL25Z Boards: Reset, SWD Clock and Low Power

Best Regards,

Robin
