HMC1035 SPI mode selection

The SPI Mode application note suggests that that SPI HMC or Open mode is selected by configuring the SEN and SCLK pins at power on of the device. The timing diagrams in the document don't show the chip enable line (CEN), can you confirm whether mode selection is irrespective of CEN line and mode selection will happen at power on reset regardless of CEN state? Or must the CEN line be high before SPI mode can be set?


Best regards,
