I can not find CK_BAD_PIN register in Si5319 datasheet

I want to use INT_CB pin of Si5319 as an LOS alarm pin, instead of interrupt pin. INT_CB pin description of data sheet Rev.1.0 in page 40 states "Set CK_BAD_PIN = 1 and INT_PIN=0", but I can not find CK_BAD_PIN register. Which address and bit is the register located?

Register 22 bit D2 is the CK_BAD_POL register and is R/W (register 22 bits D7Robot Very Happy3 are reserved)

I checked Si5324 datasheet and found CK1_BAD_PIN in Register 20 bit D2 and CK_BAD_POL in Register 22 bit D2. Does this apply to Si5319? I think the description of CK_BAD_POL does not fit to the meaning of CK_BAD_PIN.

The description and function of CK1_BAD_PIN, register 20 bit D2, listed in the Si5324 data sheet provides the same function in the Si5319.
