NOTES:
1. Relationship between system clock
φ frequency and power source voltage is shown in the graph below.
2. When the A/D converter is used, refer to the recommended operating conditions of the A/D converter.
3. 12.5 MHz
< f(XIN) ≤ 16 MHz is not available in the frequency/2 mode.
4. The oscillation start voltage and the oscillation start time differ depending on factors such as the oscillator, circuit constants, and
operating temperature range. Note that oscillation start may be particularly difficult at low voltage when using a high-frequency
oscillator.
5. When using the microcomputer in low-speed mode, set the clock input oscillation frequency on condition that f(XCIN) < f(XIN)/3.
