Register 11H (dynamic output state register)
This register can be read (or read and cleared for diagnostic bits). This register reports the
dynamic state of an output as seen at the falling edge of CSN as well as the External
MOSFET controller fault status.
EXTFx_y
These bits provide fault diagnostic information for the external MOSFET drivers. Fault
indication is limited to drain source faults. A VDS (drain-source voltage) fault is indicated if
the Drain-Source voltage exceeds the programmed value (EXTx_VDSx) for longer than the
VDS filtering time (tVDS_FILTER) the output is disabled and a fault code is set.
