Important note: When the diagnostic circuitry is enabled (one of the HSxCSEN bits is set), then the
corresponding over-current protection circuitry is not active. Therefore enabling the driver when the diagnostic
circuitry is enabled is not recommended!

Table 3.23 HSDSTAT Register Bits Description
Bit Description
HSxOSF: Open/short status flag of the high-side driver x (x = 4 to 1). This flag is not registered; i.e., its value
7:4 ^{remains as long as the diagnostic event takes place.}
Refer to Table 3.24 for the descriptions of the HSxOSF bits.
HSxOCIF: Over-current interrupt flag of the high-side driver x (x = 4 to 1).
3:0 1 = There is an over-current in the output of driver x. The driver x is disabled as long as this bit is set.
0 = There is no over-current in the output of driver x.

1) Important: The diagnostic result is correct only if the corresponding driver is switched off.
2) In the event of a short, an over-current will occur.
