SEEB:
0 = Enables EEPROM writes to SEE bytes in Table 02h (Default).
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.

AEN:
0 = The temperature calculated index value (‘T Index’) is write-able by the user and the updates of
calculated indexes are disabled. This allows the user to interactively test their modules by controlling
the indexing for the look-up 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 is auto mode). Both
DACs will update at the same time (just like auto mode).
1 = Enables auto control of the LUT (Default).
MOD-EN:
0 = “MOD DAC” is write-able by the user and the LUT recalls are disabled. This allows the user 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_C Stop condition is the end of the write cycle.
1 = Enables auto control of the LUT for modulation (Default).
APC-EN:
0 = “APC DAC” is write-able by the user and the LUT recalls are disabled. This allows the user 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_C Stop condition is the end of the write cycle.
1 = Enables auto control of the LUT for APC reference (Default).
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 the user to interactively test their
modules by writing the DAC value for bias. The output is updated with the new value at the end of the
write cycle to the “MAN IBIAS” register. The I
1 = Enables auto control for the APC feedback (Default).
