How to power down ADF5355 synthesizer blocks when using external PLL

Circuit Note 232 (CN-0232) for the ADF4350 mentions (page 5) a method for powering down the synthesizer blocks on the ADF4350 using a test mode bit (DB10, R5). I need the equivalent register and bit for the ADF5355. Our application uses an external PLL and we need to shut down the PLL function and internal counters of the ADF5355 to reduce spurious levels.
