Output Pins not working SPC574k

Hi,

I am currently working on the SPC574k Discovery board and having issues with getting an Output on most off the pins. In my attached image configuration I only get an Output on ATOM1_0, ATOM1_1, ATOM2_1 and ATOM3_0. I use the MCS Module to generate an output for each channel. I checked the code for the mcs module and if I route the signal from originally ATOM1_4 to the ATOM1_0, the correct signal apears on the ATOM1_0 Pin.

I am also not able to control a number of Pins via the normal GPIO function even when they are correctly configured.

My question, is there some additional limitation in the GPIO Matrix of the chip? Do I have to set a configuration in code to get certain pins to work or could I have a defective Microcontroller?

Kind Regards,
Sir_Alee

To give the future reader a solution, The SPC574k Discovery board has a lot of mislabel pinout. I found out that several pins are mislabled in the documentation or swapped with other pins. I checked my misbehaving pins via probing the SPC574k directly at the package and found them to be working.

Hope this helps someone.
