What is the input impedance of log ports? I'd like to understand how attaching a logic port to either a serial data receive or a serial data transmit port (both are non-standard) adversely affects the data.

Hello,
The PPK2 hardware files are available here.

The logic port is routed through an FXMA108 level shifter. I am unable to find any info in the datasheet w.r.t. input current or impedance but this is a good place to start.
Thanks,
