Connection example

note1

- When 2 DRAMs are used, the DRAM OE pins should be tied LOW.

- When single DRAM is used, the DRAM OE pin should be tied LOW

or controlled by the SM5903CF NOE signal.

note 2 When CXD 2517 (Sony) is used

Set 85H of microcontroller command (option setting) as setting YFLAG take in;

D5: YFLAGS= 1

D4: YFCKP= 0
