MK66FN2MOVLQ18 microcontroller is powered up with 3.3 Volts, Now if i will check voltage @ Vcc pins of controller it shows 3.3 volts that's fine but, if will check voltage @ GPIO Pins it shows only 1.2 Volts. So is it correct voltage @GPIO??

In my design i have used MK66FN2MOVLQ18 controller, & this controller is powered up with 3.3 Volts.Now if i will check voltage @ Vcc pins of controller it shows 3.3 Volts which is correct. But if i will check voltage @ GPIO pins it shows only 1.2 Volts. So is 1.2 Volts @ GPIO is correct value?? & JTAG Interface pins JTAG TMS & Reset & EZP CS pins shows 3.3 Volts. so is there problem in controller power??
