1. Timing Reference uses 0.7 VCC for a logic 1 and 0.2 VCC for a logic 0.
2. Interrupt request via Port 3 (P33-P31).
3. Interrupt request via Port 3 (P30).
4. SMR-D5 = 1, POR STOP mode delay is on.
5. Reg. WDTMR.
6. 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.
7. SMR D1 = 0.
8. Maximum frequency for internal system clock is 4 MHz when using XTAL divide-by-one mode.
9. For XTAL and LC oscillator, and for oscillator driven by clock driver.
