联机仿真的时候,使用外部中断,每当出现外部信号下降沿触发中断,未设置断点,程序就停止在外部中断程序的开始位置,这是正常情况么?程序不是一直运行不停止么?
frcdivd.c这个文件是用于什么情况的?文件上没有解释,内容如下
#include "double_config.h"
#include "reald.h"
#include "chunk.h"
#include "ieeemask.h"
#include "renormd.h"
#include "frcdivd.h"
#include "frcmpyd.h"
#include "frcaddd.h"
#define FIXPT(ff,rr) ((bigint)((ff)*(((bigint)1)<<(rr))))
#if (BPREAL == BPbigint)
biguns __TI_frcdivd(biguns l, biguns r)
{
#include "frcdivf1_i.h"
} /* FRCDIVF */
#elif (BPREAL == (BPbigint*2))
int __TI_frcdivd(REAL_2UNS *q, REAL_2UNS *l, REAL_2UNS *r)
{
#include "frcdivf2_i.h"
}
#else
#error "FRCDIVF not yet implemented for this size REAL"
#endif
衡祐,
不知你用的是哪个Device? 建议你直接从MSPware中导入一个IO中断基本例程,rebuild后重新测试看看。

请问这个文件是哪里来的?你调用TI lib了吗?我没有见过这个文件。
