PRODUCTION DATA
The latest measurement acquisition in Auto Measurement Mode can be retrieved using measurement readout commands, which are documented in Table 7-4, and illustrated in Figure 7-12. Once the measurement readout is complete, the HDC302x clears the measurement result. Therefore, if the next attempt to read data occurs before the following conversion attempt, the read results are +130°C for temperature and +100%RH for humidity.
As in Trigger-On Demand, if the I2C controller attempts to read the measurement results prior to measurement completion, the HDC302x responds with a NACK condition.
