Most of the hardware connections for the SCB are direct connections to specific pins. Since these connections are dedicated, I2C, SPI and UART can be connected to dedicated pins only.

Is there a way to assign one pin e.g. P0[4] both to UART RX *and* to an input pin in my logic design? When I try to assign either one in the pin editor, it removes the other assignment.

Exactly. But how did you rx/tx pins exposed on the UART block?
Oh, I see - I need to use UART [v2.30] and not UART [SCB mode].
Thanks!

I have the same issue, but i'm low on UDB resources and i need to use SCB for UART.
Can SCB RX pin be reached by other things like counters?
Or do i need to jump it to annother pin using external wire?

You mean like this (or do you need to mux pin) -

The RX/TX pins from the SCB block cannot be routed as normal signals. So when you need them for other components, you need to route them externally to another pin.

The notes seem to confirm limited pin assignment, but not dual use limitation ?
Or am I interpreting this wrong ? Note the compiler/router produced no errors
in the dual use route I showed. Question still remains, is that the use questioner
wanted ?
