Attempt to use invalid or uninitialized memory

hello
我在調試的時候出現如下問題
Error: At location FFE8 -
Error: Attempt to use invalid or uninitialized memory

Error: Interrupt processing failed.

當取消中斷的時候就不會有這些錯誤,請達人指出如何修正```
下面是我寫的代碼,初次接觸freescale,還需多努力```
功能是generate 4路,pwm,並且在TPM1TCNL到達TPM1MODL的時候產生一個中斷
此為試驗程序只做練習用```

请使用头文件中的宏：VectorNumber_Vtpm1ovf。原型如下：
#define VectorNumber_Vtpm1ovf 11

中断20是端口A的中断。

JerryBJ:
Thank you very much, I have correct it!
