/* example how setup a opcode, this opcode is 16bit long (taken from M68K)

* 0 and 1 mean normal bit, 2 mean mask bit the bit that are determent diffent
|

* thing in the opcode, example which reg so on, it can be etither 0 or 1 in
|
|
* the opcode. but a opcode have also normal bit that is always been set to
|
|
* same. thuse bit are always 0 or 1
