RE: Problems are about the MPC566's CLOCK

You have to verify not only the cycstal circuit, but also the associated
clock circuitry i.e. MODCLK, Vddsyn, Xfc, etc. Make sure your board is
coming out of reset.  Obviously the sysclock/clkout depend on values
programmed into SCCR (EBDF allows a clkout /2 option) and MF withing
PLPRCR.

	Subject: [MPC500] Problems are about the MPC566's CLOCK
	
	

	Hi everyone:
	I'm puzzled by the MPC566's CLOCK. I used the Axiom MPC566EVB
and 
	Codewarrior. I used MPC500_Quick_Start's GCT to set the system
clock on 
	40Mhz,and the same to Clockout. I debuged it in internal flash
and the 
	crystal oscillator is 4 Mhz. When I debuged it with the
MPC566EVB, it 
	is all right. But when I debuged it with my board that the
circuit of 
	crystal is same to the MPC566EVB, the Clockout output 2Mhz. Why?
Please 
	help me! What should I do? Thanks!!!
