3.4.2 Shared Interfaces / Signal Muxing

Due to the number of features available on the EVM, there are some limitations for which features can be used simultaneously. Many of the conflicts revolve around the emulation/trace functionality. When trace is selected/enabled, the following features are not accessible: Audio, Power Measurement (access from processor), reduce CAN-FD availability as well as few other items. See schematic for a complete definition of interfaces which share resources.
