Error codes

Structure

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:

 %04d-%04d

.. 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
2168-0008	Can occur when attempting to call an svc outside the whitelist

Support Errors
