But I don't understand. In my example the pin is configured such, that it's driven from a clock.
There is a corresponding bit responsible EXT_CLK 0x08. However this bit is only for Pin6 port0
But I have port0 pin4 where such bit don't exists. I've compiled the projects and it's working.
But HSIOM for this pin is 0x0, mean standard configuration.
Thanks for hint.
According to the TRM, port 4 is missing the logic for clocked / synced IOs. So you can only connected unsynchronized IO pins there.
I very happy with that news, because I'm usung port0
