OSD functions
• Screen display : 36 characters * 16 lines (by software)
• RAM : 352 words (9-bits per word)
Display area : 36 words * 8 lines
Control area : 8 words * 8 lines
• Characters
Up to 252 kinds of 16 * 32 dot character fonts (4 characters including 1 test character are not programmable)
Each font can be divided into two parts and used as two fonts (Ex. 16 * 16 dot character font * 2)
At least 111 characters need to be divide between a 16 * 17 dot and 8 * 9 dot character font to display the caption
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)
