Hi,
I read the EIC chapter very carefully but couldn't figure out one point: When does the EIC reenable other interrupts? In figure 27 I can see that it's possible that one isr is interrupted by another with higher priority. There is an arrow saying 're-enable interrupt' in the middle of isr 2. But who or what has reenabled other interrupts? Do I have to perform some action to enable interrupt nesting or the opposite way? Regards,
