Frame Control Registers-1
(Row 15, Column 01)
CH 5~CH 0
(Bit 5~0)
Character Height Control.
The vertical character size is determined by the bit 'VZ1' and VZ0'.
This six bits are available to get a proper character height by setting
a binary value. According to the value made by this six bits,
the character height is determined.
If the value is 32, the number of vertical pixel of character font is 32.
Eventually, the character height is expanded from 18 to 63.
The binary vlaue must be greater than 18.
BREN
Back Raster Blank Enable.
If this bit is high and the raster color is black, then the raster is trans-
parent.
FBLK
(Bit 7)
It determines the configuration of FBLK output pin.
When it is clear, FBLK pin outputs high during displaying characters
or rasters. Otherwise,FBLK pin outputs high only during displaying
characters.
dot 1,dot 0
(Bit 9,8)
This two bits determine the number of dots per horizontal line.
Refer to following table.
HF 2~HF 0
(Bit C~A)
The horizontal frequency information is transferred by this two bits
as following tables.
FPLL
(Bit D)
If this bit is high, the VCO block of OSD_PLL operates on full range
(4 MHz - 96 MHz).
