CONTROL REGISTER FORMAT
All control register bits are read and write accessible. The control register is recalled from parameter EEPROM
memory at power-up. Register bit values can be modified in shadow RAM after power-up. Power-up default values
are saved using the Copy Data command.

NBEN —Negative Blanking Enable. A value of 1 enables blanking of negative current values up to 25 μ V. A value of
0 disables blanking of negative currents. The power-up default of NBEN = 0.
UVEN —Undervoltage Enable. A value of 1 allows the DS2784 to enter Sleep mode when the voltage register value
is less than V UV and DQ is stable at either logic level for t SLEEP . A value of 0 disables transitions to Sleep mode in an
undervoltage condition.
