Why this is not working with 16f676 ? this code work 16f684 , that's i check on Proteus

Self explanitory....

Data Space used.... 40bytes.... pic16f767 no more.... However in PRO mode it does compile and run on both!!

its means when Data space reached upto 100.0% ,then mcu can't run .

No!.... I have compiled it and it runs just fine.... BUT!!! I use XC8 pro not lite.... It won't compile in lite mode...

I have also compiled it with HI-TECH PRO. But not runs.

show the circuit in Proteus.... Have you pulled MCLR High???

no sir , I not Have pulled MCLR High

thank u sir for giving hint .
now its working . i change MCLRE_OFF
