Description
Read / Write bit
0 = Read
1 = Read (cannot write to this register)
When reading this register, the R/W bit is 0
EEPROM CRC fault bit
0 = no fault detected (Reset value)
1 = fault detected
Reset bit
0 = no reset detected
1 = reset detected (cleared after register is read)
Charge Pump undervoltage shutdown
0 = no fault detected (Reset value)
1 = fault detected
Charge Pump undervoltage warning
0 = no fault detected
1 = fault detected (Reset value)
Overvoltage on VBAT pin
0 = no fault detected (Reset value)
1 = fault detected
Regulator Error
0 = no fault detected (Reset value)
1 = fault detected
REx bit is set if the commanded current is not reached after 8 PWM
periods
Undervoltage on Load Supply pin
0 = no fault detected (Reset value)
1 = fault detected
Overtemperature fault bits
0 = no fault detected (Reset value)
1 = fault detected
