MKE02Z64M4 at 80degree C

I am experiencing a lock-up issue when the MKE02Z64M4 is operated at 80deg. Celcius.

 

Here is my code:

 

ICS_C2 = 0x20; //BDIV=2, divide by 2
ICS_C1 = 0x04; //Set internal reference clock to FLL


/**************************************************************/
/* Trim Value is entered in the debuger configuration menu */
/* From the Debug tab, click on Advance Options. In advance */
/* Options, click on Calculate Trim. The value is stored in */
/* a memory location designated by Freescale (0x000003FF). */
/**************************************************************/

cTempIndex = 0x000003FF; //The address location of Trim value

ICS_C3 = *cTempIndex; //Load Trim Value = 35.15625 kHz, BUS Frequency is 18MHz

 


while (!(ICS_S & ICS_S_LOCK_MASK)) //Lock Status (Wait for the FLL to be stable)
{
BACKLIGHT_ON;
}

BACKLIGHT_OFF;

 

The spec's for the processor state operating temperature -40C to 105C.

 

Is there an errata for this?

 

Thank you,

Neil
