void interrupt VectorNumber_Virq IRQ_isr()
I don't know where there is the declarations of IRQ_isr().
How I can find the declarations of IRQ_isr()?
#include <hidef.h> /* for EnableInterrupts macro */
#include "derivative.h" /* include peripheral declarations */
#include "hcs08.h" // This is our definition file!
unsigned char blinking=0;
// This is the IRQ interrupt servicing routine
void interrupt VectorNumber_Virq IRQ_isr()
{
IRQSC_IRQACK = 1; // acknowledge IRQ interrupt (clear IRQF)
blinking = !blinking; // change blinking state
// IRQ interrupt is disabled to avoid bouncing noise:
IRQSC_IRQIE = 0; // disable IRQ interrupt
}
void main(void)
{
unsigned int temp;
SOPT1 = bBKGDPE; // configure SOPT1 register, enable pin BKGD for BDM
PTADD = 0; // all PTA pins as inputs
PTBDD = 0xFE; // pin PTB0 as input, PTB1 through PTB7 as outputs
PTBD = 0xC0; // turn off LED1 and LED2, clear other PTB outputs
PTAPE = BIT_5; // PTA5 pull up enabled
IRQSC = bIRQPE | bIRQIE; // IRQ pin enabled, IRQ interrupt enabled
EnableInterrupts; // enable interrupts (CCR:I = 0)
while (1)
{
if (blinking)
{
PTBD_PTBD6 = 0; // LED = on
for (temp=3000; temp; temp--); // wait for a while
PTBD_PTBD6 = 1; // LED = off
for (temp=30000; temp; temp--); // wait for a while
}
IRQSC_IRQIE = 1; // enable IRQ interrupt
}
}
