HDC2080: Output level for DRDY/INT

Dear Mistuhiro - 

Thanks for the post and welcome to E2E!

The HDC2080 DRDY/INT pin is a push pull type output, enabling is done via bit 2 of Register 0x0E, polarity is set via bit 1 of Register 0x0E (for active high or active low (default)), configured by bit settings in Register 0x07 and the status (reason for interrupt) available in Register 0x04. The level will be logic high or logic low, based on the settings and condition.  

Thanks Josh-san.

I understood that DRDY/INT's High level voltage is "VDD".
