** any unused input pins should be tied together and tied to ground through a capacitor (0.1 µF suggested), except the MIC
inputs, which should have a separate capacitor to ground if not used.
* Universal Jack™ capable. These pins may be inputs or outputs and are controlled by registers 64 and 66 (page 0). Only
pins 35/36 OR 39/41 may be used to drive headphones. It is not possible to drive 2 sets of headphones at the same time.
For use of pins 16/17 for Video, see section 8.2.11.1: page60
These signals are connected to resistors, capacitors, or specific voltages.
