Dear Sir,

             We are using K60FN512 controller.The circuit we are referring K60 Tower Board and using PE Micro programmer with Kinetis Design Studio.We are not able to Program the IC

we get an error message

We checked reset pin voltage thats around .7v. Thats low level is it.we checked  PTA4 (NMI/EZP_CS) that pin shows low level.According to some discussion in community or datasheet .if that pin low ,we cannot program.So now we use pull up resistor 10 ohm to reset pin and 47 UF capacitor to gnd.NOW that RESET pin goes high approx. 3.1 v and EZP_CS pin also goes high But problem still remains.Now also we cannot  program the IC...please tell me as soon as possible.
