Note 4: Error status
Data register D8029 reflects the error status of the 32DP-IF. In case of a general error (bit 0
= ON) the module tries to send a static diagnosis to the DP-master. In this case normal data
exchange is not possible. If bit 0 returns to the Off state, the static diagnosis message is
also reset.
The definition of the error bit is shown in the table below.

This bit is ON if one or more error bits (bit 2, 6,
