17 / 60 page 17 µPD6461, 6462 1.4.4 Display of VC2-Specified Characters When the displayed character control command specifies the VC2 channel for a character, that character is not output to the RGB or VC1 channel (display for the RGB and VC1 channels is usually the same as when display-off data is writtenNote). If background display (overall/minimum) is specified for the RGB or VC1 channel, no background is displayed for those characters for which the VC2 channel has been specified. Note In some cases, the display will differ slightly from the display-off data. Display- off data Solid data Solid data Solid data: Character for which all 12 × 18 dots are filled • When display-off data is displayed for the RGB, VC1, or VC2 channel If a character adjacent to the display-off data is rimmed or has a background, the rim or background encroaches into the area for the display- off data by one dot (minimum size). (The rim encroaches only at the filled dots at the left or right edge of the rimmed character.) • Display of VC2-specified character area for the RGB or VC1 channel If a character adjacent to a VC2-specified character is rimmed, the rim encroaches into the area for the VC2-specified character by one dot (mini- mum size). If the adjacent character has a background, however, the background does not encroach into the VC2-specified character area. • Display of VC2-specified character area for the VC2 channel If a rimmed VC2-specified character is adjacent to another VC2-specified character, the rim encroaches into the area for the latter VC2-specified character. The background does not encroach into the adjacent area (The rim encroaches only at the filled dots on the left or right edge of the rimmed character). • When a VC2-specified character area exists at the right or left edge of the entire display area (The figure shows an area at the left edge. The case of an area at the right edge is similar). Encroachment of rim or background (with a width of one dot for the minimum character size) Encroachment of rim Encroachment of background (1) – (5) (2) – (5) Background does not encroach into the VC2-specified character area.
