(5) Character color reversal specification selection

To select the specifications when the character color is reversed (valid only for RGB output).

•

Black character: Outputs an area with dots in black and prohibits framing.

•

White character: Outputs an area with dots in white and prohibits framing.

(6) Function selection

To select either of the character blinking or character left/right reversal functions.

(7) External clock frequency selelction

The external clock frequency 2 divided function is built in the

µPD6467.

•

×1 frequency mode: External clock frequency is not divided by 2 in the

µPD6467.

•

×2 frequency mode: External clock frequency is divided by 2 in the

µPD6467.

When the dot clock control bit (OSC) is “1 (External clock input)”, this function is able to use.

Example

×2 frequency mode is selected, and the external input frequency is 14 MHz, the internal dot clock

frequency is become to 7 MHz.

The default setting assumed on power application is as follows:

(1) Dot clock

= LC oscillation

(2) Vertical display start position

= 3-row unit

(3) Pin selection

= RGB + VC1 + VC2

(4) Output selection

= Option B

(5) Character color reversal specification selection = Black characters

(6) Function selection

= Character blinking

(7) External clock frequency selection

×1 frequency mode
