BIT 7
BIT 0
BIT 7
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.
BIT 6
MOD2EN:
0 = MOD2 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 MOD2. 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 MOD2 DAC.
BIT 5
QT2EN:
0 = QTs (HBIAS, TXP HI, TXP LO) for transmitter 2 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 2.
BIT 4
APC2EN:
0 = APC2 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 APC2. 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 APC2 DAC.
BIT 3
AEN:
0 = The temperature-calculated index value TINDEX is writable 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 LUTs. The recalled values from the LUTs appear in the DAC
registers after the next completion of a temperature conversion.
1 = (default) The temperature-calculated index value TINDEX is used to control the LUTs.
