28672 × 8-bits/24576 × 8-bits/20480 × 8-bits/
16384 × 8-bits for program
16128 × 8-bits for CGROM
■Random Access Memory (RAM)
: 512 × 8-bits (working area) : LC863448B/40B
384 × 8-bits (working area) : LC863432B/28B/24B/20B/16B
128 × 8-bits (working or ROM correction function)
352 × 9-bits (for CRT display)
■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)
Rounding
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
Caption • Text mode/OSD mode 1/OSD mode 2 (Quarter size) /Simplified graphic mode
• Ten character sizes ^*1
Horez. × Vert. = (1 × 1), (1 × 2), (2 × 2), (2 × 4), (0.5 × 0.5)
