OSD PROCESSOR FOR MONITOR

Preliminary
Frame Control Register 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'. 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.
FBLK
(Bit 6)
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.
HF 2~HF 0
(Bit C~A)
The horizontal frequency information is transferred by this three bits.
FPLL
(Bit D)
If this bit is high, the VCO block of OSD_PLL operates on full range
(4MHz - 96 MHz).
CP 1,CP 0
(Bit F,E)
This bit controls charge pump output current.
