很有用的CYGNAL C语言程序,

#include<c8051f020.h>
unsigned char e;






senddata(unsigned char,unsigned char);
setoff();
delay(long int);
void clock(void)			//clock det
{
	unsigned char e;
	WDTCN=0xde;				//CLOSE WDOG
	WDTCN=0xad;
	OSCXCN=0x76;			//ENABLE EXTERNAL CLK
	delay(10000);
    delay(10000);
	e=!OSCXCN&0x80;
	while(e); 
    OSCICN|=0x08;
}
void xbrs(void)				//ENABLE XBR,CEX0,INT0
{
	XBR2=0x40;
	P1MDOUT=0xFF;
}
void t0s(void)
{
	TCON=0x11;
	TMOD=0x09
}

main()
{
	clock();
	xbrs();
	setoff();
	
}
