PICKit3 and CCS 4.122

[kongfu1]

Using PICkit3, MPLab 8.66 and CCS 4.122 with PIC16F687, it always reports error during the debug (program, erase and check blank all worked fine):

PK3Err0040: The target device is not ready for debugging.
Please check your configuration bit settings and program
the device before proceeding.


And Configuration bits seems OK:

Are you using the required ICD header ? The 16F687 can't do debug
mode by itself. It requires a special header board. Go to the Pickit3
page here:
http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en538340&redirects=pickit3
Download and read the Header Specification from the links at the bottom
of the page.

My advice is to get a PIC that doesn't require a header and use it for
your debugging. Then move the project to the 16F687 later, when you
are done debugging it.

Thanks PCM.
