To ensure software backward compatibility unused or reserved bits
must be written as zeros and ignored upon read.
21 POLARITY_IN
R/W 0
Determines clk_fgpo clock sampling edge for fgpo_rec_sync and
fgpo_buf_sync inputs:
0 = use same active edge as for outputs
1 = use alternate active edge as for outputs
