Note 1.
The oscillation frequency and input frequency only indicate the characteristics of the oscillation
circuit. Refer to the AC characteristics for the instruction execution time.
2.
The oscillation stabilization time is the time until the oscillation enters a stable state after the
application of V
DD
or the release of STOP mode.
3.
When the oscillation frequency is 4.19 < f
X
5.0 MHz, PCC = 0011 should not be selected as the
instruction execution time. If PCC = 0011 is selected, 1 machine cycle is less than the specified
minimum value, which is 0.95
