GPIO Slew Rate for KL03

Hello,

I'm trying to setup my first project with MCUXpresso with MKL03Z4 SDK.

Using the pin configuration I found that some ports, configured as digital output, have a slow slew rate as default, other ones have a fast slew rate.

There's a way to align the slew rate for all the outputs?

In the manual of the MCU I found these specs:

It could be a solution to set the slew rate to "no init" to all the outputs? 

I thank you for your help!

MC

It really depends on the device, and on the pins. To my knowledge you can change or affect the slew range for some pins, but not for all.

'no init' simply means that it does not get changed/initialized after reset, so it keeps the setting out of reset.

Thank you ErichS.

So it seems that the slew rate is a factory setting that it is not possible to be changed.
