µPD6466

1.3 Display with RGB + VC1 + VC2 Pins

The

µPD6466 has three output options: A, B, and C. The following figure shows the output with each option

specified (the output is controlled by an output pin control command (refer to 3.11 Output Pin Control Command)).

Output pin control command (with MSB first (The command is input from the MSB (D15).)

(because this command is a 2-byte command, input of 16 bits is necessary when this command is input more than

once successively.)

Option C

•

Row specification control

Specify whether the character signal is output to the VC1 or VC2 pin in row units (or 12-column units).

•

Output pin control

The output of the VC1 and VC2 pins can be selected from three types, A, B, and C, by using the initial status setting

command (the blanking signal is output in the same manner).
