[PIC] Target device does not match - ICD3 MPLAB

Hi 

 

I want to debug a program on a PIC16F628A using the ICD3.

 

I have a simple program blinking a led to test the setup. 

With a PIC16F88 it works 100% but if I use a PIC16F628A it gives the
following error when I connect the debugger:

 

MPLAB ICD 3 detected

Connecting to MPLAB ICD 3...

Firmware Suite Version...... 01.28.90

Firmware type......................Midrange

CAUTION: Check that the device selected in MPLAB IDE (PIC16F628A)

is the same one that is physically attached to the debug

tool. Selecting a 5V device when a 3.3V device is connected

can result in damage to the device when the debugger checks

the device ID.

MPLAB ICD 3 Connected.

ICD3Err0086:  Target Device ID (00001060) does not match

expected Device ID (00001120). If you experience persistent

problems communicating, the ICD 3 test interface can be

used to help diagnose the problem.

Programming...

Programming/Verify complete

Running...

ICD3Err0040: The target device is not ready for debugging.

Please check your configuration bit settings and program

the device before proceeding.

 

If I use the ICD3 as programmer it programs and verify the 16F628A perfectly
and the led blinking program run normal.

 

Is this an ICD3 and PIC16F628 incompatibility problem or am I missing
something? Any help will be appreciated.

 

Here is my config and I have also set CMCON =7 to disable comparators and
set port as digital IO

    __config _XT_OSC & _WDT_OFF & _MCLRE_ON & _LVP_OFF & _CP_OFF
