1.3.1 Character signal output with output select option A

Option A

Whether a signal is output to the character signal output pin VC1 in row units can be specified by the OD0 bit

that selects an output pin. The VC2 output can be specified in character units, and the VC1 outputs only characters

for which the VC2 in the rows for which the OD0 bit is set to 1. The character specified by VC2 is not output to

the RGB and VC1 output.

Character output of VC1 channel

(specified row)

• Character information on the row

specified by clearing the OD0 bit to 0 is

output from VC1. However, the

characterspecified by VC2 is not output.

• The row specified by setting the OD0

bit to 1 is not output (fixed to low level).

• The row specified by clearing the OD0

bit to 0 is not output (fixed to low level).

• Only the character information specified

by VC2 on the row specified by setting

the OD0 bit to 1 is output from VC2.

• The character specified to VC2 is not

output.
