memdma_isr_init.c

用DSP BF533直接读写操作硬盘的源代码！源代码中有头文件指示了硬盘如何和BF533开发办接口

#include ".\h_file\system.h"

uchar aa = 0x2a;
ushort bb = 0;

EX_INTERRUPT_HANDLER( memDMA_ISR )
{
	aa = ~aa;
	*pLight = aa;
	bb++;
}


memDMA_ISR_init()
{
	ushort i;
	register_handler( ik_ivg13, memDMA_ISR );

	*pSIC_IMASK = 0x00200000;
	
//	i = *pIMASK ;
//	*pIMASK = i | 0x2000;

}
