1. T_A = -40 to 125 °C, no floating I/O, unless otherwise specified.
2. Data based on characterization results, not tested in production.
3. Measured from interrupt event to interrupt vector fetch.
To get t_WU for another CPU frequency use t_WU(FREQ) = t_WU(16 MHz) + 1.5 (T_FREQ-T_{16 MHz}).
The first word of interrupt routine is fetched 5 CPU cycles after t_WU.
4. Data guaranteed, each individual device tested in production.
