I am using CMSIS code.
I have the following ISR to blink an LED:
extern “C”{
void TIMER0_IRQHandler() {
LPC_TIM0->IR =1;
LPC_GPIO1->FIOPIN ^=(1 << 23); }}
It works perfectly!
If I swap the two statements inside the lSR ( Clear the interrupt after the toggling), IT STOPPED WORKING!!!
Any possible explanation?
Thanks
