DESCRIPTION
7 to 0
RCV2S[7:0]
These are the 8 LSBs of the 11-bit code that determines the start of the output signal
on the RCV2 pin; the 3 MSBs of the 11-bit code are held at subaddress 72H (see
Table 62). Values above 1715 (FISE = 1) or 1727 (FISE = 0) are not allowed. Leading
sync slope at CVBS output coincides with leading slope of RCV2 out at RCV2S = 49H.
