ADXL357 DRDY Output Voltage

Hello All,


I'm having a problem w/ my ADXL357 DRDY and INT outputs. They should be 3.3V, but they are outputting 1.8V instead. According to the datasheet, they should be 3.3V as I am powering VDDIO with 3.3V (datasheet spec for dc outputs is 0.8*VDDIO). MISO pin does appear to be operating at the correct voltage level, which is weird. 


Any theories what could be wrong here? My schematic is exact same as the reference document.
