33 / 48 page  Table 25. Device STATUS register Register Bit # Bit name Default Description STATUS Address 0x80 Read only 7 LOCK Indicates if the protected registers are locked: • 0: Unlocked • 1: Locked 6 5 4 3 RESET Indicates if the registers had been reset to the default (reset command or power-up): • 0: No reset • 1: Reset 2 VDS_P Indicates the VDS protection triggering: • 0: VDS protection not triggered • 1: VDS Protection triggered 1 THSD Indicates the thermal shutdown status: • 0: Device not in THSD • 1: Device in THSD 0 VCC_UVLO Indicates the VCC UVLO status: • 0: Device not in VCC UVLO • 1: Device in VCC UVLO 5.5.5.1 Command registers CLEAR and RESET are command registers. It is only allowed to set all bits to execute the command, other values are rejected. In case of read the device returns 0xFF. 5.5.5.2 Read/write registers All the registers are read and written using the I2C standard method. 5.5.5.3 Protected registers All critical registers of the device are protected against unwanted rewriting. When the content of the LOCK register does not fit the following condition: LOCK= NLOCK __________ the protected registers are read-only. When the content fits the above condition, the protected registers can be written, and the power stage is forced into safe condition: all the gate driver outputs are forced low.
