EIC re-enable interrupt (nesting)

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,
