can freely write and read these (just like ram) but they
can only hold numbers of a certain length. Lets say our
data registers can hold numbers up to 65536 (16 bits
wide). Our address registers can hold numbers up to
4294967296 (32 bit address bus) enabling us to access up
to 4096 MEGS of RAM!!!!


An example of an assembly listing (the format)

Instruction    source   destination 

LD/MOVE          D0    ,    D7

Symbols : $ tells you there is a hex number e.g CDEF =
52719

          .B (byte length (0 - 255 (dec)))
          .W (word length (0 - 65536 (dec)))
          .L (Long Word lenght ( 0 - That rather large
                                   number!!!(dec)))!!! 


This loads the contents of register D0 into the register
D7 thats your first instruction !!!
