Where:
PU = Power up bit
OR= Out of range bit
IS = Invalid scaling bit
RTS = Real time sampling bit
HF = Hardware Fault
EE = EEPROM status bits
CS = Calibration status bits
1
These bits are set (1) at approximately the input range limits selected (Table NO TAG).
In this chapter you learned the meaning of the status information that
the input module sends to the processor.
