Hi,
I am using Keil uVision to compile/link my 8051 c program but found that the vector table space is used by linker to place some code. Thus, my ISR does not function correctly.
void ISRext1(void) interrupt 2 { ... }
How can I prevent the linker from using the vector table space?
The Linker only uses the vector table space if there is nothing else using it!
So you have some other problem that is causing your ISR not to be called...
