User Parameter Rules

Some bytes of input data and output data exchanged with the DP-master (the 32DP-IF's con-
figuration) must be defined by user parameter. Also defined by user parameters are how the
exchanged data should be distributed between the available I/O points and special function
blocks. Some applications require initial settings, like gain and offset of analog blocks. For
these purposes, the 32DP-IF requires a set of parameter data, which must be determined by
the user parameter.
For "after power on" parameter, refer appendix A. For user parameter example, refer to appen-
dix B.
Note:
User parameters become valid for 32DP-IF and special function blocks (ex. FX
4DA).
