Description:
 def getStatus(self):
 """ RDY - Ready Bit. This bit provides the status of the RDY flag from the part. The status and function of this bit is the same as the RDY output pin. A number of events set the RDY bit high as indicated in Table XVIII in datasheet STDY - Steady Bit. This bit is updated when the filter writes a result to the Data Register. If the filter is in FASTStep mode (see Filter Register section) and responding to a step input, the STDY bit remains high as the initial conversion results become available. The RDY output and bit are set low on these initial conversions to indicate that a result is available. If the STDY is high, however, it indicates that the result being provided is not from a fully settled second-stage FIR filter. When the FIR filter has fully settled, the STDY bit will go low coincident with RDY. If the part is never placed into its FASTStep mode, the STDY bit will go low at the first Data Register read and it is not cleared by subsequent Data Register reads. A number of events set the STDY bit high as indicated in Table XVIII. STDY is set high along with RDY by all events in the table except a Data Register read. STBY - Standby Bit. This bit indicates whether the AD7730 is in its Standby Mode or normal mode of operation. The part can be placed in its standby mode using the STANDBY input pin or by writing 011 to the MD2 to MD0 bits of the Mode Register. The power-on/reset status of this bit is 0 assuming the STANDBY pin is high. NOREF - No Reference Bit. If the voltage between the REF IN(+) and REF IN(-) pins is below 0.3 V, or either of these inputs is open-circuit, the NOREF bit goes to 1. If NOREF is active on completion of a conversion, the Data Register is loaded with all 1s. If NOREF is active on completion of a calibration, updating of the calibration registers is inhibited."""
