Hey i am actually trying to know the state of a pin which is an external interrupt source and it.
i am using LPC2148 and trying to program that my button press interrupts the main program and jumps to ISR show LED pattern and when i hit that again it stops showing that pattern which means it jumps back to the main program.
HElp i am clue less how to do that any particular register which reads the current state of that pin which is an external interrupt source.
