READ/ RESET
BIT DESCRIPTION
WRITE VALUE
D7 R/W 0 Reserved. Write only reset value.
D6 R/W 0 0: DC measurement data update is enabled.
1: DC measurment data update is disabled. User can read the last updated data without any data
corruption.
D5 R/W 0 0: For IIR-based dc measurement, the measurment value is the instantaneous output of the IIR filter
1: For IIR-based dc measurement, the measurment value is update before periodic clearing of the IIR
filter
