这里有很多我自己做的凌阳单片机源程序

#include<spce061a_chf.h>
unsigned int Ret=0;
unsigned int count=0;
unsigned int uiData=0x0008;
void IRQ7(void)__attribute__((ISR));
void IRQ7(void)
{
	asm("int off");//关闭所以中断
	Ret=*P_UART_Command2;
	if(Ret&0x0040)
	{
		*P_UART_Data=uiData;
	}
	else if(Ret&0x0080)
	{
		count=*P_UART_Data;
	}
	asm("int irq");
}
