Notes:
1. The V_CC voltage specification of 3.0V guarantees 3.3V ± 0.3V, and the V_CC voltage specification of 5.5V guarantees 5.0V
± 0.5V.
2. 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. Maximum frequency for external XTAL clock is 4 MHz when using low-EMI Oscillator mode PCON Reg.D7 = 0.
5. Interrupt request via Port 3 (P31–P33).
6. Interrupt request via Port 3 (P30).
7. SMR–D5 = 1, POR STOP Mode Delay is on.
8. For RC and LC oscillator, and for oscillator driven by clock driver.
9. Register WDTMR.
