XDON

Display-ON input pin

When XDON = low, the VGG voltage is output all output pins irrespective of the shift data and the

content of input data. After, the contents of the shift registers becomes unfixed the data.

XON operates asynchronously with CPV. This pin is pulled-up to the VDD.

Since all LCD drive outputs output (G1 to G300) the VGG level, much current may generate them

momentarily.

When 263 / 256-pin mode, unapplied LCD panel drive pins fixed VEE.

The voltage applied to this pin must be a DC-level voltage that is either high (VDD) or low (VSS).

G1 to G300

LCD panel drive pins

These pins output the shift register data or the voltage of VGG or VEE depending on the control

signals OE and XDON.

VGG

⎯

Power supply for LCD drive

VEE

⎯

Power supply for LCD drive

VDD

⎯

Power supply for the internal logic

The (VDD) is the MODE1, MODE2 and U/D pin for connection.

VSS

⎯

Power supply for the internal logic

The (VSS) is the MODE1, MODE2 and U/D pin for connection.
