... Configuration Registers The ISD5216 is a very versatile chip where the analog audio signal can be routed and processed in a variety of ways. Writing to three configuration registers sets up the internal path. To aid the setup of the signal paths, the available paths are displayed graphically and the currently selected path highlighted in blue while the available but inactive paths are shown in gray ...
