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.
