這種設定只有上昇緣時會產生中斷。比較可行的作法是使用 :
1. Interrupt On-Pin Change 的方式，使用 RB4 ~ RB7. 2. 修改 INTEDG1 bit in the INTCON2 register (PIC18F452)，偵測捯上元產生中斷後立即修改成下降緣中斷，這樣上下緣都課以被偵測到。

Hi 請問各位大大一個笨問題
倘若我想開啟INT1 然後要EDGE改變就要中斷 我可以用這樣的語法嗎？ OpenRB1INT( PORTB_CHANGE_INT_ON & FALLING_EDGE_INT & RISING_EDGE_INT & PORTB_PULLUPS_OFF); 很笨的問題，煩請有經驗的大大能告知。 感激不盡
