Reserved.
3:1
Port used as microphone input
When combo jack detection is enabled, Port presence detection as shown in
the pin complex is not sensed directly by the sense input but is inferred by the
load placed on the Vref_Output associated with the port
000 = Port A
001 = Port B
010 = Port C
011 = Port D;100 = Port E
101 = Port F
