Description
These bits are read-only and indicate the revision of the device.
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, i.e., VBI data insertion will not work.
This bit is used to switch the DAC outputs from SCART to a EUROSCART configuration. A
complete list of all DAC output configurations is shown in Table 13.
With this active high bit it is possible to output an extra chrominance signal C, on DAC A
in any configuration that features a CVBS signal.
This bit must be set to 1 to enable Teletext data insertion on the TTX pin.
This bit enables switching of the Teletext request signal from a continuous high signal
(MR36 = 0) to a bitwise request signal (MR36 = 1).
This bit determines the default output color from the DACs for zero input pixel data (or
disconnected). A Logic 0 means that the color corresponding to 00000000 is displayed. A
Logic 1 forces the output color to black for 00000000 pixel input video data.
