12.3 List of error codes.
This chapter defines the individual error numbers. Each error number is related to a
software module. For each error number the code used in the software is defined, the
number is defined and a short description about the purpose of the software module is
given.
12.3.1 Drivers (0XX)
The driver layer contains modules responsible for direct interaction with the hardware and
some general utility routines.
