MCLR of the pic18F4553

[hayawana]

Hi guys,

I did circuit attached in image below. Im using a pic18F4553 with mikroC. I use picflash2 to load the code.

I dont understand what is happening with the mclr pin sometimes the pin goes up to 10,61 volts when i put a resistor between vcc and mclr it decreases.
But sometimes it works without it but i have to touch the wire with my hands.

Vcc is coming from usb of picflash2;

Can someone help me with it ; any ideas?

thanks

PICflash2 provide 5V needed for ICSP. You should not power up the uC board externally.
