Extended Mapping
Some applications work with data that is viewed bitwise. To make the
mapping for such applications even more flexible, an "Extended
Mapping" is provided. This mapping basically works in the same way
as the mapping described above:
Individual areas of the output Memory Register are assigned from
areas of the input Memory registers. In Extended Mapping you define
such assignments for up to 16 areas. When doing so, enter a number
of consecutive bits for each of these areas.
The limit of a register must be exceeded: The area may be up to
1024 bits long. Unlike the simple mapping described above,
however, the 16 target areas do not necessarily have to be at
consecutive addresses. You are totally free to define the position of
the first bit of the target area by entering an output register address
and the corresponding bit position (0 bis 15). The source area is also
defined by entering the input register and a start bit position.
