This section provides the basic default configuration settings for each available ACT88321 CMI option. IC functionality
in this section supersedes functionality in the main datasheet. Generating the desired functionality for a custom CMI
sometimes requires reassigning internal resources, resulting in removal of base IC functionality. The following sections
attempt to describe any removed functionality from the base IC functionality. The user is required to fully test all required
functionality to ensure the CMI fully meets their requirements.
CMI 101: ACT88321VU101-T
CMI 101 is optimized to show the many of the ICs functionality and it is intended to provide the user with a base IC for
initial testing. It is designed to operate from a 3.3V input voltage.
