因為 PIC 採用 Pipelining (管線式的指令執行) 的架構，所以 PC 會比程式目前的執行加一行。所以這是正常的現象，用 MPLAB SIM 就不會有此現象。

假設程式如下
作step over 時 執行完call DELAY後應該停在下一行 例如movlw 0x00或bra loop 但是實際上卻不會停下來 而是停在call DELAY後的第2行 請問這是正常的嗎? 晶片是pic18f452 發展工具是ICD2 ORG 0x0000 goto Main Main: clrf TRISD loop: movlw 0xff movwf PORTD call DELAY movlw 0x00 movwf PORTD call DELAY bra loop ;******************************************** DELAY: movlw 10 movwf 0x21 del1: movlw 200 movwf 0x22 del2: movlw 200 movwf 0x23 del3: decfsz 0x23 bra del3 decfsz 0x22 bra del2 decfsz 0x21 bra del1 return END
