95 / 136 page  Rev.3.02 Apr 10, 2008 Page 95 of 131 REJ03B0177-0302 38D2 Group Recommended Operating Conditions NOTES: 1. When the A/D converter is used, refer to the recommended operating conditions of the A/D converter. 2. 12.5 MHz < f(XIN) ≤ 16 MHz is not available in the frequency/2 mode. 3. 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. f: Oscillation frequency (1 MHz ≤ f(XIN) ≤ 8 MHz) of oscillator. When the 8 MHz oscillation is used, assign “8” to “f”.
