SEEB:
0 = (Default) Enables EEPROM writes to SEE bytes.
1 = Disables EEPROM writes to SEE bytes during configuration, so that the configuration of the part is
not delayed by the EE cycle time. Once the values are known, write this bit to a 0 and write the SEE
locations again for data to be written to the EEPROM.

M4DAC-EN:
0 = M4DAC is writeable by the user and the LUT recalls are disabled. This allows users to
interactively test their modules by writing the DAC value for M4DAC. The output is updated with the
new value at the end of the write cycle. The I
1 = (Default) Enables auto control of the LUT for M4DAC.
AEN:
0 = The temperature-calculated index value (T INDEX) is writeable by the user and the updates of
calculated indexes are disabled. This allows users to interactively test their modules by controlling the
indexing for the lookup tables. The recalled values from the LUTs will appear in the DAC registers
after the next completion of a temperature conversion (just like it would happen in auto mode). Both
DACs will update at the same time (just like in auto mode).
1 = (Default) Enables auto control of the LUT.
MOD-EN:
0 = MOD DAC is writeable by the user and the LUT recalls are disabled. This allows users to
interactively test their modules by writing the DAC value for modulation. The output is updated with
the new value at the end of the write cycle. The I
1 = (Default) Enables auto control of the LUT for modulation.
APC-EN:
0 = APC DAC is writeable by the user and the LUT recalls are disabled. This allows users to
interactively test their modules by writing the DAC value for APC reference. The output is updated
with the new value at the end of the write cycle. The I
1 = (Default) Enables auto control of the LUT for APC reference.
BIAS-EN:
0 = BIAS DAC is controlled by the user and the APC is open loop. The BIAS DAC value is written to
the MAN IBIAS register. All values that are written to MAN IBIAS and are greater than the MAX IBIAS
register setting are not updated and will set the BIAS MAX alarm bit. The BIAS DAC register will
continue to reflect the value of the BIAS DAC. This allows users to interactively test their modules by
writing the DAC value for I
to the MAN IBIAS register. The I
1 = (Default) Enables auto control for the APC feedback.
