Function
7 to 4
6
4-bit framing code window
every detected clock-runin loads window counter with 4-bit value * 2 (e.g. 6
→ 12-bit window)
window counter is clocked down to 0 with teletext bit rate
slicer will ignore text line if no framing code is found inside framing code window
0000 = disable framing code window
