No other “traps” I can think of off the top of my head. It is sorta standard practice to do stuff like this in embedded processors, have tons of features that share the same under the hood pins and restrict users to 1 of them. The confusing part is that the Cortex only has that happen exactly once, ports 4/10 on digital, so its something you never think about.
There are a bit deeper explanations around as for whats going on with 4/10 under the hood if anyone is curious.
