NOTE. The Group assign function becomes important if the number of data bits
(channels) increases. However, this function is not important for the DG2040
that has only two channels. This function remains for increased number of
channels in the future.
This menu is used to define groups for data bits. The pop-up menu shown in
Figure 3-56 lists the currently defined groups.

See Figure 2-6 for the group allocation.
The Add Group menu allows you to add a new group. A new group cannot be
added if there is already two groups defined.
Each data bit has a default group name. The default group names are DATA1 for
data bit 1, and DATA0 for data bit 0. You can combine several data bits into a
new group and define a new group name.
The bit structure of a group is defined by specifying the Most Significant Bit
(MSB) and Least Significant Bit (LSB) of the group. If the bit structure of a new
group overlaps with that of an existing group, the newly defined group takes
precedence and the structure of the existing group is automatically modified.
Figure 3-57 shows an example of a bit structure assignment.
