1.
Oscillator frequency and X1 input frequency indicate oscillation circuit characteristics only. See AC
CHARACTERISTICS for instruction execution time.
2.
The oscillation stabilization time is the time required for oscillation to stabilize after V
DD
reaches MIN. of
oscillation voltage range or the STOP mode is released.
3.
When the oscillator frequency is 4.19 MHz < f
XX
≤
5.0 MHz, PCC = 0011 should not be selected as the instruction
execution time. If PCC = 0011 is selected, one machine cycle is less than 0.95
μ
s and the rated MIN. value
of 0.95
μ
s is not observed.
Note
When the clock oscillator is used, the following should be noted concerning wiring in the area in the figure
enclosed by a dotted line to prevent the influence of wiring capacitance, etc.
The wiring should be kept as short as possible.
No other signal lines should be crossed.
Keep away from lines carrying a high fluctuating current.
The oscillator capacitor grounding point should always be at the same potential as V
SS
. Do not connect
to a ground pattern carrying a high current.
A signal should be not taken from the oscillator.
