MCF5282 RESET Problem

Hi,
 
It is Christie from Canada. I have the following problem:
 
When I power on MCF5282 or reset MCF5282, RSTO/ stays LOW. I tried to disable PLL(CLKMOD0,1-->GND) and use external CLK, it is same. I measure the CLK on EXTAL and XTAL, the EXTAL is about 0.928VDC, XTAL is about 0.738, but on 5282Lite board, EXTAL is about 0.684VDC, XTAL is about 0.832. Both have the CLKOUT.
 
Could somebody tell me where the problem could be?
 
Thank you very much.
 
Christie
