µPD6461, 6462

(2) For LSB-first transfer (Command bits are input starting from the LSB (D0). The function of each bit is the same as

that for MSB-first transfer.)

•

Character pattern specification bits

These bits are used to specify the address of the character pattern to be used. Address FEH (

µPD6461)/7EH

(

µPD6462) indicates display-off data and address FFH (µPD6461)/7FH (µPD6462) indicates the end code for second-

byte continuous input. The design of each character pattern can be modified by specifying a mask code option (except

for addresses FEH and FFH (

µPD6461)/7EH and 7FH (µPD6462)).

•VC2 channel specification bit

This bit is used to specify whether each character is output to the VC2 channel. Characters for which the VC2 channel

is specified are not output to the RGB or VC1 channel (This bit is invalid in RGB+3BLK mode).

•

Blinking control bit

This bit is used to enable or disable blinking for each character. Blinking of characters is turned on/off for the entire

screen with the character display control command (refer to 3.2 CHARACTER DISPLAY CONTROL COMMAND).

•

Character color specification bits

These bits are used to specify the color of each character (These bits are valid only for the RGB channel. Only

a single color can be used for the VC1 and VC2 channels).

•

Reversing control bit

This bit is used to enable or disable reversing for each character. The characters of the entire screen are reversed

with the character reverse on/off command (refer to 3.5 CHARACTER REVERSE ON/OFF COMMAND).
