Notes:
1. The V_CC voltage specification of 5.5V guarantees 5.0V ±0.5V.
2. The timing reference uses 0.7 V_CC for a logic 1 and 0.2 V_CC for a logic 0.
3. SMR: D1 = 0.
4. The maximum frequency for the external crystal clock is 4 MHz when using LOW-EMI OSCIL-
LATOR mode.
5. The interrupt request via Port 3 (P31–P33).
6. The interrupt request via Port 3 (P30).
7. SMR: D5 = 1, and the POR Stop-Mode Delay is on.
8. For RC and LC oscillators, and for an oscillator driven by a clock driver.
9. The D1,D0 column applies to the Watch-Dog Timer Mode Register tap selection.
10. 12 µs is the typical delay time.
