Dec. 2015 Rev.004 Command [READ_MASK_WLS] is used to read back data to ensure it was received correctly. Command [WRITE_LOCK] is used to lock the important registers. Command [WRITE_UNLOCK] is used to unlock the important registers. Command [READ_UNLOCK] is used to read back the data to ensure it was received correctly. Command [RESET_STATUS] can reset all bits in the STATUS register except for the REXT_FAULT_FLAG, based on command parameters, and resets the PWM_OK register (see RESET_STATUS command description). Command [READ_STATUS] is used to access all bits in the STATUS register. Command [SOFTWARE_POR] resets the chip and sets all registers to default values. POR_FLAG is set HIGH. Command [READ_PWM_OK] is used to read the PWM detection. Command [READ_Gen_SHORT] is used to read the LED short detection. Command [READ_Gen_OPEN] is used to read the LED open detection. Command [READ_SHORT_TO_GND] is used to read the short to ground detection.
