The DA_EN bit enables the DA signal on pin 9. Normally inactive, the DA output signal becomes active on new data

available: logical OR of the bits STATUS_REG[1] and STAUTS_REG[0] for humidity and temperature, respectively. The

DA signal returns inactive after both HUMIDITY_OUT_H and TEMP_OUT_H registers are read.
