you have to insert code which can do the debug of your code.
With CCS-C Compiler, i just have to write ICD=TRUE on the #device line.

Objet : [PIC]: ICD Problem


I am trying to run the ICD for the first time to check out how well the ICD
function. I have assembled a very simple program and downloaded it to a
PIC16F877. The program lights a few LED's when I push a switch.  I can
program the chip with ICD and the program works fine in stand alone mode.
  The problem is that when I select debug mode I can single step and do
animate stepping only with the fastest Upload Option: Minimum (FSR, W,
Status, PCLATH) (Very Fast) and with Minimum and watch windows, other upload
options gives communication errors.
  And if I try to run with the ICD without any breakpoints the processor
halts directly?
Also after a reset the programcounter is set to pc:0x16  shouldn't it be
zero or 0x05 where my program starts?
Have I missed something or have I problem with my serial port on my
computer?
Please give me a hint.
