Pulsed power stage.
Neighboring stages, reset, input
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).
