FYI I amended:
Note, the format definition could be named @3rf_b (for
3R with a df field BYTE-based) but since the instruction
class is named '3R', we simply call the format @3r to
ease reviewing the msa.decode file.
However we directly call the trans_msa_3rf() function,
which handles the BYTE-based df field.
