13.5 CLOCK AND TIMING CHARACTERISTICS
Subject to general operating conditions for V
13.5.1 General Timings
13.5.2 External Clock Source
Notes:
1. Guaranteed by Design. Not tested in production.
2. Data based on typical application software.
3. Time measured between interrupt event and interrupt vector fetch. ∆t
ish the current instruction execution.
4. Data based on design simulation and/or technology characteristics, not tested in production.
