Character signal

Outputs the logical OR of the character signals at

the VR, VG, and VB pins (for columns 0 to 23 in the

specified rows), excluding those characters for

which the VC2 channel has specified.

Fixed to low level (for the specified rows)

Outputs the logical OR of the character signals at

the VR, VG, and VB pins (for columns 0 to 11 of the

specified rows), excluding those characters for

which the VC2 channel has been specified.

Outputs the characters for which the VC2 channel

has been specified (for columns 12 to 23 of the

specified rows).

Outputs the logical OR of the character signals at

the VR, VG, and VB pins (for columns 12 to 23 of the

specified rows), excluding those characters for which

the VC2 channel has been specified.

Outputs the characters for which the VC2 channel

has been specified (for columns 0 to 11 of the

specified rows).

Fixed to low level (for the specified rows)

Outputs the characters for which the VC2 channel

has been specified (for columns 0 to 23 in the

specified rows).

Background signal (if specified)

Outputs a background signal for areas other than

those for which the VC2 channel has been specified.

Outputs a background signal for those areas for

which the VC2 channel has been specified.

Outputs a background signal for areas other than

those for which the VC2 channel has been specified.

Outputs a background signal for those areas for

which the VC2 channel has been specified.

Outputs a background signal for areas other than

those for which the VC2 channel has been specified.

Outputs a background signal for those areas for

which the VC2 channel has been specified.

Outputs a background signal for areas other than

those for which the VC2 channel has been specified.

Outputs a background signal for those areas for

which the VC2 channel has been specified.

The RGB and VC1 channels do not output character signals for characters for which the VC2 channel has been specified.

Background signals are output separately as listed above.

In addition, the µPD6461, 6462, when set to RGB+VC1+VC2 mode, provide the following output control:

• Independent on/off control of character display for each channel (3-channel independent display on/off command)

• Independent control of the background for each channel (3-channel independent background control command)
