Eh, wait.
The spec is not clear (at least to me) on this point:
# OR the loop position value left shifted by 8 with the External LNA Control Value
# If the External LNA Value isn't 0
1. OR the value with 0x8000
# OR this value with the table values below which are marked with Yes

But I see that one could interpret the spec in your way as well.
