为什么我把这个程序放到s12hz64里，却进不去中断呢？当然声明部分我是做了修改的
程序如下：
#include <hidef.h> /* common defines and macros */
#include <MC9S12HZ64.h> /* derivative information */
//#pragma LINK_INFO DERIVATIVE "MC9S12HZ64"

int intcount = 0;
void timer_init(void)
{
TSCR2_PR0 = 1; //prescale factor is 128
TSCR2_PR1 = 1;
TSCR2_PR2 = 1;
TSCR2_TOI = 1; //overflow enable
TFLG2_TOF = 1;
TSCR1_TEN = 1; //timer enable
}

#pragma CODE_SEG NON_BANKED
interrupt 16 void timer_interrupt_handle(void)
{
intcount++;
TFLG2_TOF = 1; //clear interrupt flag
};
#pragma CODE_SEG DEFAULT

void main(void)
{
EnableInterrupts;
timer_init();
for(;;) {}
}

dg128b的程序如下，这个可以仿真，看到intcount在不断增加

程序如下

#include <hidef.h> /* common defines and macros */

#include <mc9s12dg128.h> /* derivative information */

#pragma LINK_INFO DERIVATIVE "mc9s12dg128b"

int intcount = 0;

void timer_init(void)

{

TSCR2_PR0 = 1; //prescale factor is 128

TSCR2_PR1 = 1;

TSCR2_PR2 = 1;

TSCR2_TOI = 1; //overflow enable

TFLG2_TOF = 1;

TSCR1_TEN = 1; //timer enable

}

#pragma CODE_SEG NON_BANKED

interrupt 16 void timer_interrupt_handle(void)

{

intcount++;

TFLG2_TOF = 1; //clear interrupt flag

};

#pragma CODE_SEG DEFAULT

void main(void)

{

EnableInterrupts;

timer_init();

for(;;) {}

}

上边这个是hz64的，下边这个是dg128的，应该是一致的

#define Vtimpaie 0x0000FFDA

#define Vtimpaovf 0x0000FFDC

#define Vtimovf 0x0000FFDE

#define Vtimch7 0x0000FFE0

#define Vtimch6 0x0000FFE2

#define Vtimch5 0x0000FFE4

#define Vtimch4 0x0000FFE6

#define Vtimch3 0x0000FFE8

#define Vtimch2 0x0000FFEA

#define Vtimch1 0x0000FFEC

#define Vtimch0 0x0000FFEE

#define Vrti 0x0000FFF0

#define VReserved6 0x0000FFF2

#define Vswi 0x0000FFF6

#define Vtrap 0x0000FFF8

#define Vcop 0x0000FFFA

#define Vclkmon 0x0000FFFC

#define Vreset 0x0000FFFE

#define Vtimpaie 0x0000FFDA

#define Vtimpaaovf 0x0000FFDC

#define Vtimovf 0x0000FFDE

#define Vtimch7 0x0000FFE0

#define Vtimch6 0x0000FFE2

#define Vtimch5 0x0000FFE4

#define Vtimch4 0x0000FFE6

#define Vtimch3 0x0000FFE8

#define Vtimch2 0x0000FFEA

#define Vtimch1 0x0000FFEC

#define Vtimch0 0x0000FFEE

#define Vrti 0x0000FFF0

#define Virq 0x0000FFF2

#define Vxirq 0x0000FFF4

#define Vswi 0x0000FFF6

#define Vtrap 0x0000FFF8

#define Vcop 0x0000FFFA

#define Vclkmon 0x0000FFFC

#define Vreset 0x0000FFFE

这个应该在哪里看呢？不好意思，刚接触，问题问得比较没水平。

我把dg128下可以运行的例子，和在hz下不能进入中断的一起发上来，请帮忙看看吧

谢谢了

因为我选的芯片是hz64的，上边的这个中断如果能运行，我要运行lvi的中断。

我觉得定时器的这个应该比较简单，如果这个都不能运行，那运行lvi中断恐怕就无从谈起了。还有，不知道版主对lvi中断了解多不多，我下边这么用行不行？

lvi中断如下所示

#include <hidef.h> /* common defines and macros */
#include <MC9S12HZ64.h> /* derivative information */

/*use the LVI interrupt to watch the power supply voltage and store
important data to EEPROM memory if the low voltage is detected. The time
is critical here - the data are supposed to be programmed prior to the
low voltage reset. So, that's not possible if the voltage falls down too
quickly.
In the other words:
If the supply voltage is below the specs (below 4.5V) then the ATD
accuracy and the functionality of input/output pins is affected. The MCU
is still working fine and also we can erase/program the EEPROM or FLASH
memory. The MCU is reset if the voltage is too low - if the supply
voltage is below VLVRA threshold (low voltage reset - assert level)
which is min 2.25V (you can find the specifications - in Appendix A).

Here is simple example how to use LVI interrupt: */

#pragma CODE_SEG NON_BANKED
interrupt 57 void LVI_ISR(void)
{
if(VREGCTRL_LVDS == 1)
{
//the voltage is bellow VLVIA threshold
//store the data to EEPROM here
}
else
{
//the voltage is above VLVID threshold
//do something here if needed
}

VREGCTRL_LVIF = 1; //clear the interrupt flag
}
#pragma CODE_SEG dEFAULT

void main(void)
{
VREGCTRL_LVIE = 1; //enable low voltage interrupt
EnableInterrupts;

//do something here
for(;;){ }
}

建议你不要用中断号的方式定义中断矢量，最好用中断地址的方式，这样不容易出错。可以在PRM文件中这样定义：

VECTOR ADDRESS 0xFFDE timer_interrupt_handle

这是软件的缺陷么？还是有什么别的需要注意的地方呢？

按照这种定义改了，还是不行啊。我觉得这个问题很奇怪，不是软件哪里设置有问题吧

版主抽空看看我的源程序吧，都在附件里。

谢谢了

看来只有版主会上来回复问题啊

呵呵

用的是Full Chip Simulation,可以执行的，就是进不去中断

还有在dg128里的那个程序就可以的，我今天用hz64重新生成了一个工程，还是照旧不能进中断

改成4.7版本就可以了,真是很奇怪

时不时hz64的芯片不如dg128的常用,而软件本身也存在bug?

可能版本越高,bug也会越少吧
