State of CLK output on LTC6903/6904 when disabled

Anybody know what state the CLK output pin for the LTC6904 goes into when it is disabled (by sending a SPI/I2C command to set control bits CNF1=0 & CNF0=1)?

In our application, we need to disable the CLK output of the LTC6904.  But, the datasheet doesn't say what happens to that CLK output when it is disabled (does it go Low, High, or Hi-Z)?

Thanks!
