(Timing Register 0 TR0 = X X X X X 1 0 1)
In this mode the ADV7190/ADV7191 can generate Horizontal and Vertical SYNC signals. A coincident low transition of both
HSYNC
and
VSYNC
inputs indicates the start of an Odd Field. A
VSYNC
low transition when
HSYNC
is high indicates the
start of an Even Field. The
BLANK
signal is optional. When the
BLANK
input is disabled the ADV7190/ADV7191 automatically blanks
all normally blank lines as per CCIR-624. Mode 2 is illustrated in Figure 40 (NTSC) and Figure 41 (PAL). Figure 42 illustrates
the
