It specifies Cb/Cr frame mean values’ displacement from Cb/Cr Target (73h-74h) value where AWB
goes into LOCK state.

It specifies Cb/Cr frame mean values’ displacement from Cb/Cr Target (73h-74h) where AWB is
released from LOCK state. AWB operation retains LOCK state unless Cb/Cr frame mean values’
displacement value exceeds this boundary. The value should be larger AWB Lock Boundary.

When Cb/Cr frame mean values’ displacement from Cb/Cr Target exceeds AWB White Pixel Boundary
value, AWB accept frame color as it is and does not try to correct white balance deviation.
