Sets the STATUS bit 1 to the value of fifo_full
Uses CFG bit 2 (endian_swap) to switch input endianness

Shaked has identified an additional needed blocking condition, which I will shortly add to this PR.

A bit too late but, seems to me like the was_fifo_full field is not really needed, instead apply mask_ready to tl_o inside the let/dealy. I will do this change if you don't see anything wrong with it.
