SNAS678B May 2018 – May 2019 HDC2080
When DRDY_ENABLE is enabled and a humidity and/or temperature conversion is complete, the DRDY_STATUS bit asserts to 1. To enable the DRDY/INT pin of HDC2080, the DRDY/INT_EN bit (0x0E bit) must be set to 1 and the INT_MOD bit should be set to 0. If these bits are not configured, the pin will be left in high impedance. The INT_POL bit of this register defines the interrupt polarity of the DRDY/INT pin. Figure 8 and Figure 9 display the output behavior of the DRDY/INT pin for both interrupt polarity cases: INT_POL= 0 and INT_POL= 1.
