AD9361 RX Half Band Filters - How many output bits they have?

I wonder how many output bits AD9361 half band filters have. It says in the filter guide, for HB2 for example, full scale range is 256. Does it mean that this filter will saturate or overflow if the output gets larger then 256? Since the ADC of AD9361 is 12 bit, I think half band filters should have more output bits then 8. But it is not specified explicitly in the filter guide.

 

I will be really hapy for any kind of help. Thank you all in advance.
