Description
phase related to the signal on RCV1 or RCV2 input. The 3 MSBs are held
in subaddress 6Dh; see
1727 (FISE = 0) are not allowed. Increasing HTRIG[10:0] decreases
delays of all internally generated timing signals. Reference mark: analog
output horizontal sync (leading slope) coincides with active edge of RCV
used for triggering at HTRIG[10:0] = 4Fh (79).
Description
0 = pin RCV1 is switched to input; default state after reset,
1 = pin RCV1 is switched to output.
0 = polarity of RCV1 as output is active HIGH, rising edge is taken
when input; default state after reset,
1 = polarity of RCV1 as output is active LOW, falling edge is taken
when input.

when CBLF = 1:
0 = pin RCV2 is switched to input; default state after reset,
1 = pin RCV2 is switched to output.
0 = polarity of RCV2 as output is active HIGH, rising edge is taken
when input, respectively; default state after reset,
1 = polarity of RCV2 as output is active LOW, falling edge is taken
when input, respectively.
…continued
If ORCV2 = 1, pin RCV2 provides an HREF signal (horizontal
reference pulse that is defined by RCV2S and RCV2E, also during
vertical blanking interval); default state after reset
If ORCV2 = 0 and bit SYMP = 0, signal input to RCV2 is used for
horizontal synchronization only (if TRCV2 = 1); default state after
reset.
If ORCV2 = 1, pin RCV2 provides a ‘composite-blanking-not’ signal,
for example a reference pulse that is defined by RCV2S and
RCV2E, excluding vertical blanking interval, which is defined by FAL
and LAL
If ORCV2 = 0 and bit SYMP = 0, signal input to RCV2 is used for
horizontal synchronization (if TRCV2 = 1) and as an internal
blanking signal.
Function
Vertical Sync each field; default state after reset
Frame Sync (odd/even).
Field Sequence, vertical sync every fourth field (PAL = 0),
eighth field (PAL = 1) or twelfth field (SECAM = 1).
