MODE REGISTER 4
MR4 (MR47–MR40)
(Address (SR4–SR0) = 04H)
Figure 19 shows the various operations under the control of
Mode Register 4.
MR4 BIT DESCRIPTION
Timing Reset (MR40)
Toggling MR40 from low to high and low again resets the inter-
nal horizontal and vertical timing counters.
MODE REGISTER 5
MR5 (MR57–MR50)
(Address (SR4-SR0) = 05H)
Figure 20 shows the various operations under the control of
Mode Register 5.
MR5 BIT DESCRIPTION
Reserved (MR50)
This bit is reserved for the revision code.
RGB Mode (MR51)
When RGB mode is enabled (MR51 = “1”) the ADV7197
accepts unsigned binary RGB data at its input port. This control
is also available in Async Timing Mode.
Sync on PrPb (MR52)
By default the color component output signals Pr, Pb do not
contain any horizontal sync pulses. They can be inserted when
MR52 = “1.”
This control is not available in RGB mode.

Color Output Swap (MR53)
By default DAC B is configured as the Pr output and DAC C
as the Pb output. In setting this bit to “1” the DAC outputs
can be swapped around so that DAC B outputs Pb and DAC C
outputs Pr. The table below demonstrates this in more detail.
This control is also available in RGB mode.
Reserved (MR54–MR57)
A “0” must be written to these bits.
