AD7864: Chip Select Inputs

Other inputs on the AD7864 (#STBY, #WR and Chip Select Inputs SL1 & SL2) are
going to be pulled high via pull-up resistors. Do these lines need to be pulled
high to the +3.3V supply or to the main +5V supply (DVDD)?

 

These can be pulled to the 5V supply, through pullups.
