Where: PU = Power up unconfigured state
FP = Field power off
CF = Configuration mode
BD = Calibration bad
DN = Calibration accepted
P0 and P1 = Output holding in response to Q0...Q1
W0 and W3 =Wire off current loop status for channels 0 and 1 respectively. (Not used on voltage outputs).
U0 and U1 = Underrange for input channels 0 and 1 respectively
V0 and V1 = Overrange for input channels 0 and 1 respectively
EN = Enable outputs; 0 = output follows S1/S0, 1 = output enabled
IC = Initiate configuration bit
TR = Transparent bit
IT = Interrupt toggle bit
Q0 and Q1 = Hold
RV = Revert to defaults bit
QK = Quick calibration
