Hello,
I am using FRDM DEV BRD KEAZ128 and S32.
I am trying to understand how interrupts are working. Lets take as example from FRDM-KEA-QSP package example project Lab5_ADC_KEA128 where ADC generates interrupt after every conversion. How does processor understands what it needs to go to void ADC_IRQHandler() function ? This function is not described in the main(). Can I give for interrupt handler function any name (for example my_adc_irq () ) or it must have fixed name? If yes where are these names described ?
int main(void)
{
/* Initialize Core Clock to 40MHz, Bus Clock to 20MHz */
Clk_Init();
/* Configure button pins as inputs and LED pins as outputs */
GPIO_Init();
/* Initialize the ADC module and read at Channel 10 and 8bit conversion mode is imposed */
ADC_Init(10,0);
/* Enable FTM2 interrupt */
Enable_Interrupt(ADC_IRQn);
while(1);
return 0;
}
Best Regards,
IB

Hi
Customer could find the __isr_vector table located at <startup_SKEAZ1284.S> file.
It will indicate the ADC module interrupt service routine related ISR function is ADC_IRQHandler.
Wish it helps.
Have a great day,
