rtc interrupt every sec whilst continuing count

Hi,

I wish to program the RTC of MC9S08pa16 to generate an interrupt every second where I compute some data whilst the RTC keeps counting. How do I do that?

Thanks,

Avdit

Hi Avdit,

From your description it seems that you need a periodic interrupt of 1 sec using RTC. For this you can use PE ->Init_RTC module, set the clock source as 1-KHz Low Power Oscillator, clock gate -> Enabled, Prescaler -> 100, Modulo Value -> 9. In the interrupts section, you must enable the interrupt and give the name of the ISR that you may define in your application.

Hope this answers your question.
