STW type definitions
Used types like 'word', 'long' or 'dword' are mistakable. They can have a different meaning, depending on the
platform where they are used.
The meaning of 'word' means 16 bits at a 16-bit controller like the Infineon C167 or the Freescale 68k. At a 32-
bit controller like the used TriCore processor 'word' means 32 bits. On TriCore hardware 16 bits are called a
'halfword' instead.
To avoid confusions STW introduced clear types like 'uint16'.
