PIC16F1575在未检测到模拟器的情况下检测到下降沿中断

好，请保持温和，因为我可能犯了一个愚蠢的错误，所以请帮忙；）MPLABX 3.40XC8 1.38WIN7 Pro 6.1当前使用模拟器（绿点应该可以）和刺激。我希望uC检测PORTC3ConfigurePortinitialize falledge Enableinter.s.（TMR1工作良好）刺激。

    OK, be gentle because I've probably made a stupid mistake here, so help ;)
MPLABX 3.40
XC8 1.38
WIN7 Pro 6.1

Currently using the simulator (green dot so should be OK) and stimulus.

I want the uC to detect a falling edge on PORTC3

Configure the port
    // set port C 0,1,2 as digital output
    TRISCbits.TRISC0=0;
    TRISCbits.TRISC1=0;
    TRISCbits.TRISC2=0;
   
    // set port C 3,4,5 digital as input
    TRISCbits.TRISC3=1;
    TRISCbits.TRISC4=1;
    TRISCbits.TRISC5=1;

Initialize falling edge
//-----------------------------------------------------------------------------
// SWITCH Initialize
//-----------------------------------------------------------------------------
// Initialize the action button switch

void InitSwitch (void){
   
    IOCCNbits.IOCCN3=0x01; // enable falling edge PORTC3

return;
}


Enable the interrupts.
   // enable interrupts
    INTCONbits.IOCIE=0x01; // interrupt on change Port C2
    INTCONbits.PEIE=0x01; // interrupt on peripheral trigger
    INTCONbits.GIE=0x01; // enable global interrupts

Interrupt. (the TMR1 works fine).
//-----------------------------------------------------------------------------
// FUNCTION : interrupt main_int(void)
// PURPOSE : interrupt vector code
//-----------------------------------------------------------------------------
/* Determines which device interrupt was triggered and calls the respective handler.*/

void interrupt main_int(void)
    {
        // Handle Timer1 interrupt
        if (TMR1IE && TMR1IF){
            ISRTimer1();
            }
        // Handle PortC3 interrupt
        if (IOCIE && IOCCF3){
            ISRSwitch();
            }
    return;
    }


The stimulus.
