MPLAB X中的模拟器不会中断

我在MPLAB X版本4.10中遇到了一个问题，下面的代码在MPLAB 8.92中工作，但在MPLAX中没有，因为我已经设置了它。代码使用PIC16F616，从CCP1的特殊事件触发器在比较模式下产生中断，time1在FoSC／4上计时。代码以绝对寻址方式组装。我看到的问题是：1）即使CCP1IF标志设置为预期，也不会中断。2）如果我修改代码简单地轮询CCP1IF标志，它会按预期工作，但是秒表显示每次中断时应该有1个额外的周期。这是一个累积误差，所以秒表的时间随着错误的增加而漂移，虽然这几乎不重要，因为中断从来没有被拿走！在MPLAB 8.92中，我很容易就明白了这一点，但是我对MPLAB的旧版本有更多的经验，虽然不是很长时间。有很多事情我喜欢MPLAX X，但模拟器的工作是一个至关重要的功能对我来说！我有可能设置不正确的东西吗？谢谢，克里斯，-----------------------------------用Time1ListP=16F616，S=On，x=on，n＝0，r＝十进制包含，Eng& Gt；定义了FrasQualTeSEC标志，0Cbx0x20tQualTeStac；四分之一秒中断计时器；Sorg 0x04 Goto启动Org 0x004 Goto ISR启动CLRF PORTA CLRF PORTCBSF状态，RP0 CURRF安塞尔；没有模拟输入MOVLW 0；设置I/O模式MOVWF TrISA MOVLW 0；设置I/O模式MOVWF TISISC BCF状态，RP0CRF TQTROSEC CLRF TSLCRF RTMLCLAF标志；设置T1；设置T1 PRESCAER到1：8 BCF T1CON，TMR1BSF T1CON，T1CKPS1 BSF T1CON，T1CKPS0CRF RTM1LCRF TMR1H；设置CCP MOVLW 0x0B；用于比较模式产生特殊事件MOVWF CCP1CON；设置为62500，每250000毫秒MOVLW 0xF4 MOVWF CPR1H MOVLW 0x024 MOVWF CPR1LBSF状态，RP0BSF PIC1，CCP1IE；启用CCP1中断BCF状态，RP0 BSF ITCN，PEIE；启用外围中断BSF ITCCON，GIE BSF T1CON，TMR1 on CLRF PIR1主环路BTFSC，QualQualTSEC GOTO四分之一GOTO主环四分之一BCF QualQualTSEC调用增量定时器GOTO主回路增量定时器ICOF TQUActhSac BTFSS TQualTSEC，2 RealCurrTQTeSEC，CIF TS秒MOVLW。60亚WTs秒，W BTFSS状态，Z RealCurrf TS秒，IF f Tmin MOVLW。60次WTF Tmin，W BTFSS状态，Z RealCelRF Tmin IF返回。WF WTEMOP SWAPF状态，W MOVWF STATUSSIN TEMPBCF状态，RP0 BCF PIR1，CCP1IF BSF FrasQualTSEC；恢复W和状态寄存器，从中断SWAPF StasuSuMTEP返回，W MOVWF状态SWAPF WYTEMP，F SWAPF WYTEMP，W RESFIE；

    I'm having a problem with the simulator in MPLAB X version 4.10
The code below works as expected in MPLAB 8.92, but not in MPLAB X as I have set it up. The code uses a Pic16F616, generating interrupts from the special event trigger of CCP1 in compare mode, with Timer1 clocked at Fosc/4. The code is assembled with absolute addressing. The issues I see are:
1) The interrupt is never taken, even though the CCP1IF flag is set as expected.
2) If I modify the code to simply poll the CCP1IF flag, it works as expected, but the stopwatch shows 1 extra cycle every time the interrupt should have been taken. This is a cumulative error, so the stopwatch time drifts with increasing error, though this hardly counts since the interrrupt was never taken!
I was impressed at how easily I got this going in MPLAB 8.92, but I do have a lot more experience with the older versions of MPLAB, though not for a long time. There are a lot of things I like about MPLAB X, but having the simulator work properly is a vital function for me! Is it possible I have something set up incorrectly?

Thanks, Chris
