9. LSI LAYOUT AND ADDRESS MANAGEMENT

Addresses are managed so that up to four µ PD16664s can be used to organize a liquid crystal display of 416 x 320

pixels.

Four modules can be connected on the same bus with the /CS, /WE, and /OE pins shared.

The system can treats one screenful of the liquid crystal display as one memory area, and does not have to decode

more than one LSI.

Specify an LSI No. by using the PL0 and PL1 pin to determine the layout of the LSIs, and determine the direction

(vertical or horizontal) of the liquid crystal display by using the DIR pin.
