This is the out line in C of the direct memory in the C programming
langauge. The trick is, or course, to now fill out the binary reads
inside the structures, which is not easy. C is a BYTE centered
langauge.
It will take to create masks of the unisigned chars with a bitwise AND
mask?
For example, the offset is the last 3 bits so
0000 0000 0000 0111 is a mask for the last 3 bits?
