System Configuration Example
An example of configuring a liquid-crystal panel of VGA half-size (480
×
320 dots lengthwise) by using four LSIs
and two row drivers.
Each column driver sets the LSI No. with PL0, PL1 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 a resistor for the oscillator to the OSC1 and OSC2 pins of the master. Leave the OSC1 and OSC2 pins of
the slave open.
The signals from the system (D0 through D15, A0 through A16, /CS, /OE, /WE, /UBE, RDY, /RESET, and /DOFF)
are connected to all the column drivers in parallel. Connect a pull-up resistor to the RDY signal.
The TEST pin is used to test the LSI. Open or connect this pin to GND when the system is configured.
