Interrupt on Nuvoton NUC100LD2DN

Rifai Fai

Hi, I'm newbie on keil & I'm trying learn ARM Cortex-M0 from Nuvoton. I confuse how to use interrupt on timer funtion. How i can get interrupt from overflow? I'm familiar before with AVR, on atmel studio for interrupt I just call function

 ISR(TIMER1_OVF_vect )
{
  PORTB |= _BV(0);
  reti();
}

And how about nuvoton?
Help me please..

    Normal Function, ie no magically entry/exit requirements to save context, or return-from-interrupt

    extern volatile uint32_t SystemTick;

/**
  * @brief  This function handles SysTick Handler.
  * @param  None
  * @retval None
  */

#define TICK_RATE 1  // in milliseconds

void SysTick_Handler(void)
{
  // Free running millisecond counter for timeouts

  SystemTick += TICK_RATE; // 1 ms tick count
}
