These have been redesigned from the 3DS so that they fit within a Aarch64 MOV instruction immediate most of the time (without requiring the additional MOVK).

Bits Field
8-0 Module
21-9 Description

When a fatal-error is received the error code is outputted using the following formatter:


.. where the first code is 2000 + Module, and the other being Description. Bits >=22 from the error-code are unused when displaying fatal-errors, since the Description ends with bit21.

Fatal Errors

Error Description
2162-0002 Can be triggered by running svcBreak. The svcBreak params have no affect on the value of the thrown error-code.
2168-0000 Userland ARM undefined instruction exception
2168-0001 Userland ARM prefetch-abort due to PC set to non-executable region
2168-0002 Userland ARM data abort. Also caused by abnormal process termination via svcExitProcess. Note: directly jumping to nnMain()-retaddr from non-main-thread has the same result.
2168-0003 Userland PC address not aligned to 4 bytes
