I'm not sure about this one.

The TRM has this for the ANAMICL register:
Analog microphone left: Main microphone, headset microphone, carkit
microphone, or auxiliary left microphone can be routed to the input of the
A/D converters separately (only one enable bit at 1).

It is true, that it does not states explicitly that you can not set more than
1 bit, but it has this: only one enable bit at 1...

Are you sure about this?
