Notes:
1. Vcc = 1.8 V to 5.5 V and Topr = -20 °C to 85 °C (N version)/-40 °C to 85 °C (D version), unless otherwise specified.
2. The average output current indicates the average value of current measured during 100 ms.
3. For details, see Table 4.10 High-Speed On-Chip Oscillator Circuit Electrical Characteristics.
4. For details, see Table 4.11 Low-Speed On-Chip Oscillator Circuit Electrical Characteristics.
5. The pins with high drive capacity are P1_2, P1_3, P1_4, P1_5, P3_3, P3_4, P3_5, and P3_7.
