SYSTEM CONFIGURATION EXAMPLE

An example of configuring a liquid-crystal panel of half-VGA size (480 across by 320) by using four column drivers

and two row drivers.

• Each column driver sets the LSI No. with PL0, 1, and 2 pins.

• The DIR pins of each column driver are all set to low level.

• Only one of the column drivers is set to the master; all the others are set to the slave. Signals are supplied from

the master column driver to the slave column driver and to the row driver.

• Connect an oscillator resistor to the OSC1 and OSC2 pins on the master, and leave these pins open on the slave.

• All the signals from the system (D0 to D15, A0 to A16, CSB, OEB, WEB, UBEB, RDY, RESETB, and DOFFB) are

connected in parallel to the column driver. Connect a pull-up resistor to the RDY signal.

• The TEST pin is used to test the LSI, and is open or grounded when the system is configured.
