Notes:

1. The VCC voltage speciﬁcation of 3.0V guarantees 3.3V ± 0.3V, and the VCC voltage speciﬁcation of 5.5V guarantees 5.0V

± 0.5V.

2. Timing Reference uses 0.7 VCC for a logic 1 and 0.2 VCC 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.
