Getting illegal_isr When Executing the F28069 Adc_Tempsensorconv example program

Hi,

i am using F28069PZA Experimental kit, When i am executing the Adc_Tempsensorconversion example program i am getting ILLEGAL_ISR. After debugging this program it is saying this ILLEGAL_ISR.

In this program the equation for calculating the degc is degC = GetTemperatureC(temp); like this

int16 GetTemperatureC(int16 sensorSample)
{
    return ((sensorSample - getTempOffset())*(int32)getTempSlope() + FP_ROUND + KELVIN_OFF)/FP_SCALE - KELVIN;
}

#define getTempOffset() (*(int (*)(void))0x3D7E85)()

#define getTempSlope() (*(int (*)(void))0x3D7E82)() 

what doe these two address locations stands for in OTP and how much the value in those Function address.

Thanks & Regards

Vinay
