AR 0700 to AR 0703 and AR 0704 to AR 0707 are used to designate word
allocations for operating levels 0 and 1 of the SYSMAC LINK System. Alloca-
tion can be set to occur either according to settings from a Peripheral Device
(e.g., FIT) or automatically in the LR and/or DM areas. If automatic allocation
is designated, the number of words to be allocated to each node is also des-
ignated. These settings are shown below.

The above settings are read every cycle while the SYSMAC LINK System is
in operation.
AR 08 through AR 11 and AR 12 through AR 15 provide flags that indicate
which nodes are active in the SYSMAC LINK System at the current time.
