HMC960 parallel port pins

Hi,

 

if using the SPI port to control the HMC960, should the parallel port pins left open or can they be tied together and grounded via resistor, while bit[5] of reg. 02h is set to 1?

In addition I would like to use the decoded gain value set in reg 03h without interference by the parallel port inputs.

At the moment it seems, that parallel port pins are overriding the SPI settings.
