Control Register Definitions (Continued)
Bits 7–2
Reserved. These should be set to zero.
Vertical Blank Duration Register:
VBLANKDUR (0x8403)
Res’d
Vertical Blanking Duration
X
VB[6:0]
Bits 6–0
This register determines the duration of the vertical blanking signal in scan lines. When vertical blanking is enabled,
it is recommended that this register be set to a number greater than 0x0A.
Bit 7
Reserved. This bit should be set to zero.
OSD Character Height Register:
CHARHTCTRL (0x8404)
CH[7:0]
Bits 7–0
This register determines the OSD character height as described in the section Constant Character Height
Mechanism. The values of this register is equal to the approximate number of OSD height compensated lines
required on the screen, divided by 4. This value is not exact due to the approximation used in scaling the character.
Example: If approximately 384 OSD lines are required on the screen (regardless of the number of scan lines) then
the Character Height Control Register is programmed with 81 (0x51).
