• Manufacturer: Analog Devices, Inc.

MODE REGISTER 4
MR4 (MR47–MR40)
(Address (SR4–SR0) = 04H)
Figure 55 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 56 shows the various operations under the control of Mode
Register 5.
MR5 BIT DESCRIPTION
Reserved (MR50)
These bit is reserved for the revision code
RGB Mode (MR51)
When RGB mode is enabled (MR51 = “1”) the ADV7196A 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. If required 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. Table X demonstrates this in more detail.
Reserved (MR54–MR57)
“0” must be written to these bits.
