SDO status
Note:
In case of a status change during an SPI transmission this status will not be read and
therefore not cleared in case of a clear command.
Due to the internal mechanism of loading the status data into the shift register a possible
inconsistency between the GlobalErrorRegister and the read StatusRegister can occur. In
this case, the data in the Status Register is always the more actual data.
No (chip reset or
communication error)
Active low
Activated by all internal reset events which
change the device state or configuration
registers (e.g. software reset, VCORE3
undervoltage, etc.). This bit is initially '0' and will
be set to '1' by a valid SPI communication to any
register.
Over temp/ over load
Active high
Set when over temp and/or over load failure is
detected by the diagnosis function
n/a
0
Not implemented
Open-load
Active high
Set when open-load failure is detected by the
diagnosis function
STK_ON
Active high
Set when SHORT TO BATTERY is detected by
the diagnosis function (OFF state diagnosis)
Fail save
Active high
Indicates if the device is in FAIL SAVE (defined
state)

CSN

SDI
SDO
CSN high to low and SCK stays low: status information of data bit 0 (fault condition) is transfered to SDO
time
SDI: data is not accepted
SDO: status information of data bit 0 (Global Error Flag) will stay as long CSN is low
