Debug disable in NONMAIN can be re-enable using default password
If debug is disabled in NONMAIN configuration (DEBUGACCESS = 0x5566), the device can still be accessed using the default password.
1. Set the DEBUGACCESS to Debug Enabled with Password option (DEBUGACCESS = 0xCCDD) and provide a unique password in the PWDDEBUGLOCK field. For higher security, it is recommended to have device-unique passwords that are cryptographically random. This would allow debug access with the right 128-bit password but can still allow some debug commands and access to the CFG-AP and SEC-AP.
2. Disable the physical SW Debug Port entirely by disabling SWDP_MODE. This fully prevents any debug access or requests to the device, but may affect Failure Analysis and return flows.
