Unused Pins

Table TBD shows how to connect the devices unused

pins when circuit blocks are disabled. If the system is

extremely noisy or there is a concern that unused analog

inputs might be enabled, then alternatively unused analog

audio inputs can be AC coupled to AGND (if component

cost and area allow it).
