It seems to be impossible to use pin P5_3 as an output.
Although I haven't found anything in the datasheet/user manual that confirms this.

This Pin is of the special I type and linked to the I2C functionality but it can be configured as a standard GPIO pin.
The I type pins can not select the GPIO mode setting (pull-up, pull-down, ...) but I assumed it could be used as a standard output pin.
Which seems to be impossible.

Anyone who has an explanation?
Or am I still missing something.
