Hi all,
I am facing a problem while debugging the code. The following error is comming and it is jumping to disassembly
Error message is
*** 65: access voilation at 0X001B: no 'execute/read' permission
This location is Timer 1 interrupt routine.
My code is as follows
Please tell me where I am wrong as I am stuck to it solving from last so many days and not getting any solution.
Thanks in advance.
