HL (horizontal lock indicator); selectable via HLSEL (subaddress 11H, bit 4)
HLSEL = 0: standard horizontal lock indicator
HLSEL = 1: fast horizontal lock indicator (use is not recommended for
sources with unstable timebase e. g. VCRs)

DL (vertical and horizontal lock and colour detected)
PLIN (PAL/SECAM sequence; LOW: PAL/DR line is present)
HREF_HS, horizontal reference signal: indicates valid data on the
VPO-bus. The positive slope marks the beginning of a new active line.
The pulse width is dependent on the data type selected by the control
registers LCR2 to LCR24 (subaddress 41H to 57H; see Tables 4 and 61)
data type 0 to 6, 8 to 15: HIGH period 1440 LLC-cycles (720 samples;
see Fig.28)
data type 7 (upsampled raw data): HIGH period programmable in LLC8
steps via HSB7 to HSB0, HSS7 to HSS0 (subaddress 06H and 07H), fine
position adjustment via HDEL1 to HDEL0 (subaddress 10H, bits 5 and 4)
HS, programmable width in LLC8 steps via HSB7 to HSB0 and
HSS7 to HSS0 (subaddress 06H and 07H), fine position adjustment in
LLC2 steps via HDEL1 to HDEL0 (subaddress 10H, bits 5 and 4)
