6.4.8.2 Error Codes

During the boot process, the device may encounter error conditions that prevent it from completing initialization. In such cases, the Boot ROM issues a 32-bit error code, which is written to the DSU.BCC register. The DSU.BCC register retains the last value written by the device, allowing the user or debugger to inspect the cause of the boot failure.

Note: Error code values start with 0xEEEEnnnnn. The presence of an error code indicates that the boot operation was interrupted and the first mutable application executable code was not executed.
