Note:
1. Devices with 8 KB of Flash or less use RJMP instead of JMP, which takes only two clock cycles.
12.3.2.4 Interrupt Priority
All interrupt vectors are assigned to one of three possible priority levels, as shown in the table. An
interrupt request from a high priority source will interrupt any ongoing interrupt handler from a normal
priority source. When returning from the high priority interrupt handler, the execution of the normal priority
interrupt handler will resume.
