/**
* Error code layout.
*
* Currently we try to keep all error codes within the negative space of 16
* bytes signed integers to support all platforms (-0x0000 - -0x8000). In
* addition we'd like to give two layers of information on the error if
* possible.
*
* For that purpose the error codes are segmented in the following manner:
*
* 16 bit error code bit-segmentation
*
* 1 bit - Intentionally not used
* 3 bits - High level module ID
* 5 bits - Module-dependent error code
* 6 bits - Low level module errors
* 1 bit - Intentionally not used
*
* Low-level module errors (0x007E-0x0002)
*
* Module Nr Codes assigned
