As shown in example 1, 0 is entered into any unused area that creates a gap
in another area. Such an area cannot be used for any other purpose. If there
is more than 1 byte that do not create a gap in any other area, such as in word
4 in example 2, then they can be used for other purposes.

Unused
Nothing will be input into this unused area.
If there is more then one unused byte that does
not create gaps in any area, then it can be used
for another purpose.
The following kinds of data can be allocated for the Master. The Programming
Device can be used to freely select the kinds/combination of data allocated. If
the Programming Device isn't used to select the data pattern, the default set-
ting is used, which is I/O data + Communications Unit Status Flags (pattern
number 1 in the following table).
#3 #3 #4 #4 #5 #5
ID4 ID4 ID4 ID4 ID4 ID4
8 8 0 0
0 0 #1 #1
#2 #2
#5 #5 #4 #4 #3 #3
A 0 will be entered into the unused areas.
These areas cannot be used for any other
purposes.
