The generation of the timing reference codes can be suppressed by setting OFTS[2:0] to 010; see
sequence is replaced by the standard ‘- 80 - 10 -’ blanking values.
If raw samples or sliced data are selected by the line control registers (LCR2 to LCR24), the Y samples are replaced by CVBS samples.

The relationship of LCR programming to line numbers is described in

The data type selections by LCR are overruled by setting OFTS2 = 1 (subaddress 13h
bit D2). This setting is mainly intended for device production test. The VPO-bus carries the
upper or lower 8 bits of the two ADCs depending on the OFTS[1:0] 13h[1:0] settings; see
Table
a Y/C mode is selected, the expansion port carries the multiplexed output signals of both
ADCs, and in CVBS mode the output of only one ADC. No timing reference codes are
generated in this mode.
Remark: The LSBs (bit D0) of the ADCs are also available on pin RTS0; see
The SAV/EAV timing reference codes define the start and end of valid data regions. The
ITU-blanking code sequence ‘- 80 - 10 - 80 - 10 -...’ is transmitted during the horizontal
blanking period between EAV and SAV.
The position of the F-bit is constant in accordance with ITU 656; see
Table
The V-bit can be generated in two different ways (see
via OFTS1 and OFTS0; see
The F and V bits change synchronously with the EAV code.

This data type is defined for future enhancements. It could be activated for lines
containing standard test signals within the vertical blanking period. Currently the most
sources do not contain test lines. The nominal levels are illustrated in

within the Y time slots.
The amplitude and offset of the CVBS signal is programmable via RAWG7 to RAWG0
