Decoder Configuration, Byte 1:
Several decoder properties are set with CV29.
Changes are easiest if done in binary mode, but
can also be done by adding together the decimal
values (shown in parenthesis) for all the desired
features and writing the total into CV29. (For an
example, see the section of this manual that is
entitled Converting Values of Individual Bits
within a CV into an Equivalent Decimal Value for
the Entire CV.)
The definitions for the individual bits of CV29 are
given below.
