Is there an internal pullup of SPI data out?

I have a 10k pulldown on SPI SDO. I am seeing this pin sit at 1V when the device is not driving SDO, as if there is a pullup inside the device. There is nothing mentioned in the datasheet. When the device is transmitting on SDO the signals look fine....

Based on some other forum posts I can see with reasonable certainty that this pin is indeed held internally high. This is not mentioned anywhere in the current data-sheet, which advises that this pin can be held high or low to set different addresses...
