1.4.2 Character Signal Output When Option B is Selected

Option B

The VC1 channel outputs characters of all rows regardless of setting of the VC1 and VC2 bits. Each character can be

specified to be output to the VC2 channel, and the VC2 channel outputs only characters for which the VC2 channel in the rows

for which the VC1 bit is set to 1. Characters for which the VC2 channel is specified are not output to the RGB or VC1 channel.
