原廠解釋
With version 3.0 we have added a new feature called the managed PSV pointers, with this the compiler will automatically manage multiple PSV pages. If not specified, a function will be defined in the auto_psv section, which is what this warning indicates. 意思就是說3.0以後的版本增加了一個point去維護多個PSV分頁。 因為標頭檔沒有宣告PSV的model要用那個，所以警告訊息告訴我們有使用到auto_psv的功能。 因為_ISR定義為 #define _ISR __attribute__((interrupt)) 我是直接改寫標頭檔 #define _ISR(PSV_MODEL) __attribute__((interrupt,PSV_MODEL)) 以Timer1為例，若要用auto_psv就宣告成 void _ISR(auto_psv) _T1Interrupt(void); 若不用auto_psv void _ISR(no_auto_psv) _U1RXInterrupt(void); 這樣就不會有警告訊息了。

p24fj128ga008 Compiler 後,預到Interrupt 都會出現
warning: PSV model not specified for '_CNInterrupt'; assuming 'auto_psv' this may affect latency warning: PSV model not specified for '_U1TXInterrupt'; assuming 'auto_psv' this may affect latency warning: PSV model not specified for '_T1Interrupt'; assuming 'auto_psv' this may affect latency 請問有無消除方法
