These are the 8 LSBs of the 11-bit code that determines the end 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 trailing slope of RCV2 out at RCV2E = 49H.
This bit is reserved and must be set to a logic 0.
These are the 3 MSBs of end of output signal code; see Table 61.
This bit is reserved and must be set to a logic 0.
These are the 3 MSBs of start of output signal code; see Table 60.
Start of signal on pin TTXRQ; see Fig.23.
Indicates the delay in clock cycles between rising edge of TTXRQ output and valid
data at pin TTX.
Advanced composite sync against RGB output from 0 to 31 LLC clock periods.
Vertical sync shift between RCV1 and RCV2 (switched to output); in master mode it is
possible to shift Hsync (RCV2; CBLF = 0) against Vsync (RCV1; SRCV1 = 00)
standard value: VS_S[2:0] = 3.
PAL: TTXHS[7:0] = 42H
NTSC: TTXHS[7:0] = 54H
minimum value: TTXHD[7:0] = 2
