If parameters are assigned that deviate from the boundary conditions indicated above,
they are ignored by this ADI4 DP slave, as parameters are fixed internally. The ADI4 DP
slave establishes cyclic communication with the DP master using the preset values (and
not the assigned parameters) without an error message.
If a parameter assignment that deviates from the boundary conditions indicated above is
downloaded to this ADI4 DP slave, the ADI4 DP slave does not establish cyclic
communication with the DP master.
