dsPIC 30F4011 使用app020 產生address error trap

因使用dsPIC 30F4011 使用app020 demoboard 產生address error trap
debug 時有些問題如下
1. 將程式program至demoboard上run 約2秒產生address error trap
2. 將程式利用icd2在debug模式直接 run 約2秒一樣產生address error trap
3. 將程式利用icd2在debug模式在主程式設定中斷點後run每次都可以停在中斷點上不會產生address error trap
4. 利用debug 觀看W14,w15 堆疊暫存器當進入MAIN()時
w14:09a2 , w15:09a4
5. 進入外部斷時w14:09B2 , w15:09B2
6. 進入AD中斷時w14:09a2 , w15:09ac
7. 進入TIMER中斷時w14:09BE , w15:09BE
8. 進入address error trap中w14:09BA, w15:09BA
Q1 : 因程式BUG產生address error trap不知是否和這些有關
Q2 : W14不是STACK FRAME POINT 它會隨程式中斷改變嗎
請有經驗大大幫忙! 謝謝!
