When
RESET
becomes active the ADV7190/ADV7191 reverts to
the default output configuration (see Appendix 8 for register
settings). The ADV7190/ADV7191 internal timing is under the
control of the logic level on the NTSC_PAL pin.
When
RESET
is released Y, Cr, Cb values corresponding to a
black screen are input to the ADV7190/ADV7191. Output
timing signals are still suppressed at this stage. DACs A, B, C
are switched off and DACs D, E, F are switched on.
When the user requires valid data, Pixel Data Valid Control is
enabled (MR26 = 1) to allow the valid pixel data to pass through

encoder timing is now under the control of the Timing Registers.
If at this stage, the user wishes to select a different video standard
to that on the NTSC_PAL pin, Standard I

C Control should be
enabled (MR25 = 1) and the video standard required is selected
by programming Mode Register 0 (Output Video Standard
Selection). Figure 31 illustrates the
