Character specification

Specify the addresses of the 256 types of characters in each bank. Note, however, that addresses FEH

and FFH are respectively fixed to Display Off Data and a 2-byte successive command end code (these

addresses are also fixed when characters are changed by using a mask code option, and no characters

can be stored to these addresses). The design of the characters can be created by using a mask code

option.

•VC2 output specification

The character output from the VC2 pin can be specified in character units. The character specified by VC2

is not output from the RGB output or VC1 output channel (this specification is invalid when RGB + RGB

compatible BLK output selected).

•

Blinking control (character units)Note

Whether the character written to the video RAM blinks is specified in character units. Blinking is turned

ON/OFF in screen units by using the character display control command (refer to 3.2 Display Control

Command).

•

Left to right reverse character specificationNote

Left to right reverse can be turned ON/OFF in character units (this specification is valid when left and right

reverse is turned ON by the display control command).

Note

Character blinking or character left to right reverse, whichever selected by the initial setting

command, is valid.

•

Character color control

A character color can be set in units of one character (valid for RGB output only. The color is fixed for the

VC1 and VC2 output).

•

Character color reverse specification

It can be specified whether the color of a character can be reversed or not, in character units. Turning ON/

OFF the character color reverse is specified in screen units by the character color reverse ON/OFF

command (refer to 3.5 Character Color Reverse ON/OFF Command).
