BIT 2
MOD1EN:
0 = MOD1 DAC is writable by the user and the LUT recalls are disabled. This allows the user to
interactively test their modules by writing the values for MOD1. The output is updated with the new
value at the end of the write cycle. The I2C STOP condition is the end of the write cycle.
1 = (default) Enables automatic control of the LUT for MOD1 DAC.
BIT 1
QT1EN:
0 = QTs (HBIAS, TXP HI, TXP LO) for transmitter 1 are writable by the user and the LUT recalls are
disabled. This allows the user to interactively test their modules by writing to the QT thresholds.
The thresholds are updated with the new values at the end of the write cycle. The I2C STOP
condition is the end of the write cycle.
1 = (default) Enables automatic control of the LUT QTs for transmitter 1.
BIT 0
APC1EN:
0 = APC1 DAC is writable by the user and the LUT recalls are disabled. This allows the user to
interactively test their modules by writing the values for APC1. The output is updated with the new
value at the end of the write cycle. The I2C STOP condition is the end of the write cycle.
1 = (default) Enables automatic control of the LUT for APC1 DAC.

Holds the calculated index based on the temperature measurement. This index is used for the address during lookup
of Tables 04h and 06h. Temperature measurements below -40NC or above +102NC are clamped to 80h and C7h,
respectively. The calculation of TINDEX is as follows:
Temp_Value 40 C
TINDEX

For the temperature-indexed LUTs (2NC), the index used during the lookup function for each table is as follows:
