Notes:

1. Data based on typical application software.

2. Time measured between interrupt event and interrupt vector fetch. ∆tc(INST) is the number of tCPU cycles needed to finish

the current instruction execution.

3. Data based on design simulation and/or technology characteristics, not tested in production.
