timer1.c

这里有很多我自己做的凌阳单片机源程序

//TimerA, 0.5 second, IOB output
#include<spce061a_chf.h>
main()
{
					 
	*P_IOB_Dir=0xFFFF;  				//IOB Initial: OutPut			   
	*P_IOB_Attrib=0xFFFF; 
	*P_IOB_Data=0x0000; 								
	
	*P_TimerB_Ctrl=0x0001; 	//TimerA:24.576/256MHz
	*P_TimerB_Data=0xFDFF;	
	*P_INT_Ctrl=0x0400;				//Open Interrupt
	asm("INT IRQ");			 			//0.5 Second   
	while(1)						 
	{
		Watchdog_Clear();
	
	}
}
