The force out of frame (FOOF) bit forces out of frame condition. When a logic 1 is written to
FOOF, the framer block is forced out of frame at the next frame boundary regardless of the
framing pattern value. The OOF event initiates re-framing in an upstream frame detector.
The ALGO2 bit selects the framing pattern used to determine and maintain the frame
alignment. When ALGO2 is set to logic 1, the framing pattern consist of the 8 bits of the first
A1 framing bytes and the first 4 bits of the last A2 framing bytes (12 bits total). This
algorithm examines only 12 framing bits; all other framing bits are ignored. When ALGO2 is
set to logic 0, the framing patterns consist of 12 A1 framing bytes and 12 A2 framing bytes.
