Where :

EN = Enable bit (not used on input module)

IC = Initiate Configuration bit

TR = Transparent bit

IT = Interrupt toggle bit

CH - Chop Mode Disable — use to disable the chop mode. Chop mode used by the module to reduce offset and drift errors. The

default is chop mode enabled (0).

SK = FIR Filter Disable — use to disable the FIR filter. The Finite Impulse Response filter is used by the module to improve signal

stability. The default is FIR filter enabled (0).

FS = Fast Step Response — use to enable a fast step response algorithm. The fast step response algorithm, upon sensing a step

input, uses an averaging method rather than the FIR filter. The FIR goes back into operation once the input has settled. The default is

fast step response disabled (0).

RV = Revert to default bit

QK = Quick calibration

CK = Calibration clock

GO = Gain Offset select
