Enhanced TV microcontrollers with
On-Screen Display (OSD)

19.16 RGB brightness control
A brightness control is provided to allow the RGB upper
output voltage level to be modified. The nominal value is
1 V into a 150
resistor, but can be varied between
0.7 and 1.2 V.
The brightness is set in RGB Brightness Register.

19.17 Contrast reduction
CC:
This feature is not available in CC mode.
TXT
: The COR bits in SFRs TXT5 and TXT6 control when
the COR output of the device is activated (i.e. pulled
LOW). This output is intended to act on the TVs display
circuits to reduce contrast of the video when it is active.
The result of contrast reduction is to improve the
readability of the text in a mixed teletext and video display.
The bits in the TXT5 and TXT6 SFRs allow the display to
be set up so that, for example, the areas inside teletext
boxes will be contrast reduced when a subtitle is being
displayed but that the rest of the screen will be displayed
as normal video.
20 MEMORY MAPPED REGISTERS (MMR)
The memory mapped registers are used to control the
display. The registers are mapped into the microcontroller
MOVX address space, starting at address 87F0H and
extending to 87FFH.
