Where: PU = Power up unconfigured state
FP = Field power off
CF = In configuration mode
BD = Calibration bad
OR = Reference calibration signal is out of range
P0 thru P3 = Outjput holding in response to Q0 thru Q3
W0 thru W3 = Wire off current loop status for channels 0 thru 3 respectively. (Not used on voltage outputs.)
EN = Enable outputs; 0 = output follows S1/S0, 1 = output enabled
IC = Initiate configuration bit
TR = Transparent bit
IT = Interrupt toggle bit
Q0-3 = Request for outputs to hold
RV = Revert to defaults bit
QK = Quick calibration
CK = Calibration clock
GO = Gain offset select
