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

4.2
If pin 7 is selected as input, RCV2 signal can
carry just line synchronization information like
horizontal sync HS, or input data gating
function like HREF or CBN. The horizontal
re-trigger function and the data input gating
function can be utilized seoarately, or they
combined. The actual function of RCV2 input
is defined via the CBLF bit, ORCV2 bit,
PRCV2 bit and TRCV2 bit, all in subaddress
6Chex. Table 7 describes signal meaning and
effect of RCV1 as input at pin 6.
Pin 7 as Input:
RCV2
