signals of the power stages, VDD-
monitoring, SPI interface (incl. reg-
isters) and µsec-bus must not be
disturbed. Diagnostics of fault con-
ditions at neighboring stages is still
possible. Control bits in the SPI
registers (serial control of power
stages are not disturbed).
Open load failure at neighboring
stages may be detected as short
to ground
