Reserved (MR27)
A Logic Level 0 must be written to this bit.
MODE REGISTER 3 MR3 (MR37 TO MR30)
(Address [SR4 to SR0] = 03H)
Mode Register 3 is an 8-bit-wide register. Figure 41 shows the
various operations under the control of Mode Register 3.
MR3 BIT DESCRIPTION
Revision Code (MR30 to MR31)
These bits are read-only and indicate the revision of the device.
VBI Open (MR32)
This bit determines whether or not data in the vertical blanking
interval (VBI) is output to the analog outputs or blanked. VBI
data insertion is not available in Slave Mode 0. Also, when both
BLANK input control and VBI-open are enabled, BLANK input
control has priority; that is, VBI data insertion does not work.
DAC Output (MR33)
This bit is used to switch the DAC outputs from SCART to a
EUROSCART configuration. A complete table of all DAC output
configurations is shown in Table 12.
Chroma Output Select (MR34)
With this active high bit it is possible to output YUV data with a
composite output on the fourth DAC or a chroma output on the
fourth DAC (0 = CVBS; 1 = CHROMA).
Teletext Enable (MR35)
This bit must be set to 1 to enable teletext data insertion on the
TTX pin.
TTXREQ Bit Mode Control (MR36)
This bit enables switching of the teletext request signal from a
continuous high signal (MR36 = 0) to a bit wise request signal
(MR36 = 1).
Input Default Color (MR37)
This bit determines the default output color from the DACs for
zero input pixel data (or disconnected). A Logic Level 0 means that
the color corresponding to 00000000 is displayed. A Logic Level 1
forces the output color to black for 00000000 pixel input video data.
