2. Oscillator characteristics only. Refer to the description of AC characteristics for instruction execution time.
3. Oscillation stabilization time is a time required for oscillation to become stabilized after V
time.
If " PCC = 0011 " is selected, 1 machine cycle becomes less than 0.95 s, with the result that the specified MIN.
value of 0.95 s cannot be observed.
