The applications of the words in the CPU Bus Link Area and DM Area that are
allocated to SYSMAC LINK Units are described in the following tables.
The words allocated in the CPU Bus Unit Area to a SYSMAC LINK Unit are
used to access the status of the SYSMAC LINK System as shown in the fol-
lowing table.
