This application note shows how to implement the authenticated debug on the PSOC Edge MCUs. It includes the procedures for disabling the debug access ports, configuring the authenticated debug, and accessing them using the debug certificate. Additionally, it introduces the debug policies, debug access ports, how boot code enforces the debug policy, and how the debug ports can be opened by the Boot firmware using the certificates or by a trusted firmware. This application note also provides the best practices for configuring the debug access ports for in-field use cases.
