Description
Reserved.
1 = save the first flag ID to EEPROM when the device shuts down.
0 = do not save the first flag ID to EEPROM when the device shuts down.
These bits determine the retry wait time before the next soft start. Each LSB = 588 ms.
1 = reload the contents of EEPROM.
0 = do not reload the contents of EEPROM.
1 = 2.56 μs.
0 = 660 μs.
1 = ignore the VDD 3.3 V overvoltage fault.
0 = do not ignore the VDD 3.3 V overvoltage fault.
