The pin can be configed by a register write, however the controling bit
sets it on a port wide basis, so all other pins in that port would be forced
to LVTTL as well.
Hi Dana, I'm sorry, I missinterpreted the behaviour of the SCB component and the Creator software. I thought that it's not possible to access the pin features because they're buried inside the component. I didn't think about simply modifying the corresponding port registers *ouch* However, it's getting even better: it seems that the SCB component also creates API files for the pins used. That means that not 'port x.y' has to be modified, but simply 'uart_1_rx' - great :) Regards, Ralf
