MODE REGISTER 4
MR4 (MR47–MR40)
(Address (SR4–SR0) = 04H)
Figure 24 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 25 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 ADV7195
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 facility is only available when Output Stan-
dard Selection has been set to EIA-770.2 (MR01–00 = “00”) or
Full Input Range (MR01–00 = “10”).
This control is not available in RGB mode.
MODE REGISTER 3
MR3 (MR37–MR30)
(Address (SR4–SR0) = 03H)
Figure 23 shows the various operations under the control of
Mode Register 3.
MR3 BIT DESCRIPTION
HDTV Enable (MR30)
When this bit is set to “1,” the ADV7195 reverts to HDTV mode
(refer to HDTV mode section). When set to “0” the ADV7195
is set up in Progressive Scan Mode (PS Mode).
Reserved (MR31–MR32)
A “0” must be written to these bits.
DAC A Control (MR33)
Setting this bit to “1” enables DAC A, otherwise this DAC is
powered down.
DAC B Control (MR34)
Setting this bit to “1” enables DAC B, otherwise this DAC is
powered down.
DAC C Control (MR35)
Setting this bit to “1” enables DAC C, otherwise this DAC is
powered down.
Interpolation (MR36)
This bit enables the second stage interpolation filters. When this
bit is enabled (MR36 = “1”), data is sent at 54 MHz to the DAC
output stage. After Reset it is recommended to toggle this bit.
Before toggling this bit, 3Ehex must be written to address 09hex
to guarantee correct operation.
Reserved (MR37)
A “0” must be written to this bit.
