FB_STATUS[3:0] Details for ADV7403/ADV7181

We are using both the ADV7403 and the ADV7181 parts and need to read the current value of the FB pin via software.

 

The manual for both chips, however, is inconsistent with regards to the FB_STATUS readback values.  Both manuals define the current FB pin status FB_STAT as FB_STATUS[1] in the Analogue Front End section of the manual, but as FB_STATUS[2] in the I2C Register Map (similarly, FB_FALL is also swapped between the two sections).

 

So, can I get an official clarification of the correct bit positions?
