Pinouts for Interfaces

The programming connector pin functions are different for various devices and interfaces. Refer to the following pinout tables for debug and data stream interfaces.
Note: Refer to the data sheet for the device you are using as well as the application notes for the specific interface for additional information and diagrams.
