Paired outputs
Defines whether the outputs are controlled individually or whether they are controlled as paired
outputs. If the outputs are defined to act using paired operation writing the value 0 to output N
causes output N to become active and output N+1 to become inactive. Writing value 1 to output N
causes output N to become inactive and output N+1 to become active. In paired mode only the
even (0, 2, 4, ...) outputs can be addressed.

Forced output function
Defines the forced operation of outputs executed regardless of the actual command data. E.g. if
the forced function is "short pulse" and command data requires "persistent value" short pulse is
generated.
