Description
This bit controls whether the ADV7174/ADV7179 is in master or slave mode.
These bits control the timing mode of the ADV7174/ADV7179. These modes are
described in more detail in the 3.3 V Timing Specifications table.
This bit controls whether the BLANK input is used when the part is in slave mode.
These bits control the addition of a luminance delay. Each bit represents a delay of
74 ns.
This bit is used to set the pixel port to accept 8-bit or YCrCb data on Pins P7–P0.
0 must be written here.
Toggling the TR07 from low to high and to low again resets the internal timing
counters. This bit should be toggled after power-up, reset, or changing to a new
timing mode.
