Problem with the SSP1BUF register

[ADGAN]

Hi! I converted a code written for PIC18F65J90 to PIC18F45K22. The original code is as follows:

 void Output(UINT8 Data)
{
unsigned char ClearBuffer;

    while(SSPSTATbits.BF ==1)
        ClearBuffer = SSPBUF;
    
    SSPBUF = Data;
    PIR1bits.SSPIF = 0;
    Nop();
    Nop();
    Nop();
    Nop();
    Nop();
    Nop();
    Nop();
    Nop();
    Nop();
    Nop();
    while(!PIR1bits.SSPIF);
    Nop();
    Nop();
    ClearBuffer = SSPBUF;
    
    return;
}

My code is this:

void Output(UINT8 Data)
{
unsigned char ClearBuffer;

    while(SSP1STATbits.BF ==1)
        ClearBuffer = SSP1BUF;
    
    SSP1BUF = Data;
    PIR1bits.SSP1IF = 0;
    Nop();
    Nop();
    Nop();
    Nop();
    Nop();
    Nop();
    Nop();
    Nop();
    Nop();
    Nop();
    while(!PIR1bits.SSP1IF);
    Nop();
    Nop();
    ClearBuffer = SSP1BUF;
    
    return;
}

But when I simulate the original code in Proteus I see some data is been moved on the data bus. But when I test my code I don't see any data on the data bus. What could be the reason for this? I'm using MPLAB C18.

How is Init_Delay() declared? Maybe is a matter of simulation timing... the code reach a stall state inside this function.
Check the oscillator and the timestep in simulation.

Sorry there is no Init_Delay in the code.
