//established on 2004/04/14
//CA320240F and  lcd(SED1330/1335/1336) compatible provided
//pin1:GND
//pin2:VCC
//pin3:V0(adjust contrast ratio of LCD)
//pin4:A0(Data Type Selecton) connect to A1
//pin5:WRn     connect to P3.6/WRn of 8031
//pin6:RDn     connect to P3.7/RDn of 8031
//pin7:DB0 	   connect to D0
//...		   ...
//pin14:DB7	   connect to D7
//pin15:CSn    connect to 74138 output Y2n,also as 8031 address of 0x4000
//			74138 input A connect to 8031 P2.7(A15),B to P2.6(A14),C to P2.5(A13)
//pin16:RESETn,   not used
//pin17:VOUT(-20V)
//pin18:SEL1   connect to GND,as work on 8080 mode.(connect to VCC as the 6800 mode,not used)
//D0-D7 is the data bus,and A0-A15 is the address bus(so you must use a 74373)
