Each bit of the MB7..MB0 field
controls writing (=1) or no writing
(=0) of the indicated DB bits when
the M bit of the COLM packet is one.
Each bit of the MA7..MA0 field
controls writing (=1) or no writing
(=0) of the indicated DA bits when
the M bit of the COLM packet is one.
When M=1, the MA and MB
fields control writing of
individual data bytes.
When M=0, all data bytes are
written unconditionally.
