[sdiy] USB-C Alternate Mode analog signalling

Hi all,
does USB-C Alternate Mode prohibit / enable a receiving port from
dedicating one of the reconfigurable pins to an analog signal? I would
only be using this between my own devices, but I wanted this to stay
roughly standards compliant.

If the receiving device signals an alternate mode via USB PD that the
sending device is not compatible with, will the sending device be
completely prohibited from sending signals over the reconfigurable
pins?

Thanks.
