0=Disables nINT pin output function (default)
1=Enables nINT pin output function
Bit[3]
nINT Voltage Enable (EMC6D100 only)
0=Out-of-limit voltages do not affect the state of the nINT pin (default)
1=Enable out-of-limit voltages to make the nINT pin active low
Bit [4]
Offset Register Configure
0= offset register configured to the external temperature channel. (Default)
1= offset register configured to the internal temperature channel.
Bit[5]
Number of measurements of each temperature and voltage reading made.
0= take 128 separate measurements of the data from the analog block for both remote diode temperature
readings before averaging the result and storing it in the value register for remote diode temperature
measurements; take 8 separate measurements of all other voltage and internal temperature readings
before averaging.
1 =use 16 averaging for both remote diode temperature readings and no averaging for all other voltage
and internal temperature values. Setting this bit to ‘1’ would be used for power saving. (Default)
Bit[6]
Enable interrupt status register status bit to indicate remote diode 1 thermal error alarm and fault.
0=disable 1=enable (default)
Bit[7]
Enable interrupt status register status bit to indicate remote diode 2 thermal error alarm and fault.
0=disable 1=enable (default).

These registers become read only when the Lock bit is set. Any further attempts to write to these registers
shall have no effect.
This register is used to enable the voltage events to set the corresponding status bits in the interrupt status
registers.
This register contains the following bits:
