Voltage question

    Hello, I hope someone help me.

    According to special, at CCLK = 600 MHz internal supply voltage is 1.2v. After meaturing, the voltage beside power is 1.2v, while it is 1.0v beside TS201. Why does it drop from 1.2v to 1.0v? Is it right?

    Though it look like abnormal, it can step into emulator. I can't explain it and very depressed.
