Diagnosis

Output Status Monitor diagnostic is available when VS = VS(NOR) and VDD ≥ VDD(UV).

Due to the fact that Output Status Monitor checks the voltage level at the outputs in real time, for Open Load

in OFF diagnostic it is necessary to synchronize the reading of DIAG_OSM register with the OFF state of the

channels.

Figure 26, Figure 27 and Figure 28 and Figure 29 shows how Output Status Monitor is implemented at

concept level.
