User Parameter Rules
Some bytes of input data and output data exchanged with the DP-master (the 32DP-IF's
configuration) 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 default user parameter, refer to section 7.2.
Note:
User parameter data become valid for 32DP-IF and special function blocks (ex. FX
FX
-4DA).
