fonts.
• Various character attributes
Character colors : 16 colors (analog mode : l Vp-p output) /8 colors (digital mode)
Character background colors : 16 colors (analog mode : l Vp-p output) /8 colors (digital mode)
Fringe/shadow colors : 16 colors (analog mode : l Vp-p output) /8 colors (digital mode)
Full screen colors : 16 colors (analog mode : l Vp-p output) /8 colors (digital mode)

Underline
Italic character (slanting)
• Attribute can be changed without spacing
• Vertical display start line number can be set for each row independently (Rows can be overlapped)
• Horizontal display start position can be set for each row independently
• Horizontal pitch (bit 9 to 16) *1 and vertical pitch (bit 1 to 32) can be set for each row independently
• Different display modes can be set for each row independently
