Clock and synchronization signals of SAA7187 and SAA7188
Application note for digital video encoder
May 1994

4.1
If pin 6 is selected as input, RCV1 signal
could carry field synchronization information
in a form like vertical sync VS, or frame sync
FS, or field sequence identification FSEQ.
The actual re-trigger function of RCV1 input
is defined via the two SRCV1 bits, TRCV2
bit, ORCV1 bit and PRCV1 bit, all in
subaddress 6Chex, and the PAL bit in
subaddress 61hex. Table 6 describes signal
meaning and effect of RCV1 as input at pin 6.
Pin 6 as Input: RCV1

F = relevant function, x = other function/signal definition, – = don’t care
