I have an external interrupt that is generated every second from an PCF8583 clock chip. In this routine I read the time from the clock.
Is it possible to disable this interrupt from time to time e.g. when I'm in an data entry routine where I can correct and set the time in the clock chip ?
How would you do that ? I don't want to disable interrupt generally because my data entry routine depends on interrupts too.
Can I do this by modifying the external interrupt mask register (EIMSK) ?
