0 1 0 1 0 0 1 1 0 0 0 0 EOD EOT EOP EOO

EOD : Demultplexed output synchronization control

(0 : Internal HSYNC sychronization)

(1 : DISP synchronization)

EOT : Demultiplexed output timing control

(0 : Synchronized timing + 0 clock)

(1 : Synchronized timing + 1 clock)

EOP : Demultiplexed output phase control

(0 : Synchronized output)

(1 : 2-phase output)

EOO : Straight/demultiplexed output control

(0 : Straight output)

(1 : Demultiplexed output)

[Function]

This function controls screen display output.

[Additional information]

• By setting the straight/demultiplexed output selection to demultiplexed output (EOO = 1) , the display signal is

output in parallel from the DA3-0, VOBA pins and the DB3-0, VOBB pins.

• When the demultiplexed output synchronization control selection is “Internal HSYNC synchronization” (EOD

= 0) , the horizontal sync operating edge selection is determined by the horizontal sync operating edge setting

(HE bit) in the input/output pin control 1 command (command 13-0) .
