12. EXAMPLE SYSTEM CONFIGURATION
The following example shows the configuration of a system using four
μ
PD16663 LSIs and two row drivers to
drive a half VGA size (480 x 320 dots, landscape) LCD panel.
ì
The LSI No. is set for each column driver using the PL0 and PL1 pins.
ì
The DIR pin on each column driver is set to low.
ì
One of the column drivers is specified as the master; the remaining are all slaves. The master column driver
supplies signals to the slave column drivers and the row drivers.
ì
An oscillator resistor is attached across the OSC1 and OSC2 pins of the master, while those of the slaves are
left open.
ì
The signals issued by the system (D
0
to D
15
, A
0
to A
16
, /CS, /OE, /WE, /UBE, RDY, /RESET, /DOFF) are
connected in parallel to all the column drivers. A pull-up resistor is connected to the RDY signal.
ì
The TEST pin is used for testing the LSI, so either leave it open or connect it to GND when configuring the
system.
