SUBSYSTEM CLOCK OSCILLATOR CHARACTERISTICS (T

DD
= 2.0 to 6.0 V)
Notes 1.
Indicates only oscillation circuit characteristics. Refer to
AC Characteristics
for instruction execution time.
2.
Time required to stabilize oscillation after V
DD
has reached the minimum oscillation voltage range.
Cautions
1.
When using the subsystem clock oscillator, wiring in the area enclosed with the broken line should
be carried out as follows to avoid an adverse effect from wiring capacitance.
Wiring should be as short as possible.
Wiring should not cross other signal lines.
Wiring should not be placed close to a varying high current.
The potential of the oscillator capacitor ground should be the same as V
SS
.
Do not ground it to the ground pattern in which a high current flows.
Do not fetch a signal from the oscillator.
2.
The subsystem clock oscillation circuit is designed as a low amplification circuit to provide low
consumption current, causing misoperation to noise more frequently than the main system clock
oscillation circuit. Special care should therefore be taken to wiring method when the subsystem
clock is used.
