Analog Ref. Source  Sets the power-on default value of the Analog Reference Mode, 
refer to Figure 3-44. NOTE: Resistive and 4-20mA source is not 
applicable to external OVP programming.

Voltage Ref. Mode  Sets  the  power-on  default  value  of  the  Voltage  Reference 
Mode,  refer  to  Figure  3-45.  When  external  Ref.  Source  is 
selected as Resistive, FSC (Full Scale) unit will change to k 
Ohms. When external Ref. Source is selected as 4-20mA, FSC 
will not be applicable.

Curr. Ref. Mode  Sets the power-on default value of the Current Reference Mode, 
refer to Figure 3-46. When external Ref. Source is selected as 
Resistive, FSC (Full Scale) unit will change to k Ohms. When 
external Ref. Source is selected as 4-20mA, FSC will not be 
applicable.
