* 1. Oscillator characteristics only. Refer to the description of AC characteristics for details of instruction
execution time.
2. Time required for oscillation to become stabilized after VDD application or STOP mode release.
3. When oscillation frequency is " 4.19 < fX ≤ 5.0 MHz ", do not select " PCC = 0011 " as instruction execution
time. If " PCC = 0011 " is selected, 1 machine cycle becomes less than 0.95 µs, with the result that the
5
specified MIN. value of 0.95 µs cannot be observed.
