I2c Pic32

[Makaram]

Hi guys, still trying to chip away at pic32 i2c and the TCM8240 Camera found at sparkfun.
My I2C knowledge is lacking and I can't figure out why I'm getting stuck after my stop bit.

void TPI2CStop(void)
{
    int x = 0;
    // wait for module idle
     I2CIdle();
    //initiate stop bit
    CONbits.PEN = 1;

    //wait for hardware clear of stop bit
    while (CONbits.PEN)
    {
        I2CWait(50);
        x++;
        if (x > 1) break;
    }

    CONbits.RCEN = 0;
   // IFS0bits.MI2C3IF = 0; // Clear Interrupt
    STATbits.IWCOL = 0;
    STATbits.BCL = 0;
    // wait for module idle
    I2CIdle(); << STUCK HERE **********************************

}

here my I2cIdle() func

void I2CIdle(void)
{

    UINT8 timeout = 150;
    /* Wait until I2C Bus is Inactive */
    while (CONbits.SEN || CONbits.PEN || CONbits.RCEN ||
            CONbits.RSEN || CONbits.ACKEN || STATbits.TRSTAT || timeout-- );
}

CONbits.PEN is the bit which is stopping my loop from breaking..
from the pic32 family reference manual

PEN: Stop Condition Enable bit
In I2C Master mode only
1 = Initiate Stop condition on SDAx and SCLx pins; cleared by module
0 = Stop condition idle

I assume that if I'm getting this far, e.g. receiving ACK from camera, that communication is working?

what could be the problem? thanks for any assistance
