No.A0117-2/18

Continued from preceding page.

• IIC-bus compliant serial interface circuit (Multi-master type)

• ROM correction function

• 12-source 8-vectored interrupt system

• Integrated system clock generator and display clock generator

Only one X’tal oscillator (32.768kHz) for PLL reference is used for both generators

TV control and the Closed Caption function

All of the above functions are fabricated on a single chip.

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

: 16colors (analog mode: lVp-p output ) / 8colors (digital mode)

Character background colors : 16colors (analog mode: lVp-p output ) / 8colors (digital mode)

Fringe / shadow colors

: 16colors (analog mode: lVp-p output ) / 8colors (digital mode)
