ERIVATIVE REGISTERS
Determine the character size and vertical position of Row 0 (the first display row).
Determine the horizontal position of Row 0 and the selection of background and blanking functions.
Character size. The state of these two bits enable one of four possible character sizes to be
selected for Row 0. Character sizes include background. See Table 23.
Vertical position control.
The vertical position of Row 0 is selected by the state of the 6 bits, VP00 to VP05.
For details see Section 12.7.1 “Vertical position”.
Blanking. This bit enables or disables the character display. When BLK0 is set to:
Background. This bit determines whether the background display is selected or not.
The visual effect of background versus no background is shown in Fig.26. When VB0 is set to:
Horizontal position control.
These 6 bits determine the start position of Row 0.
The horizontal position control is only active during OSDC clock cycles.
For details Section 12.7.2 “Horizontal position” and Fig.25.

Logic 1, the outputs VOW1, VOW2, VOW3 and VOB are enabled; characters are displayed.
Logic 0, the outputs VOW1, VOW2, VOW3 and VOB are disabled; no characters are displayed.
Logic 1, the characters in this row are displayed with background.
Logic 0, the background is disabled and only the characters are displayed.
