When the external oscillator option is selected (figure 2-3)
Keep the length (L
OSC
) of the line between the external
oscillator and the IC clock input pin (OSC1) as short as
possible.
Also keep the length (L
OSC
) of the lines between the
external oscillator and the V
DD
and V
SS
used as short as
possible.
Other common points:
Keep signals that change rapidly and large-amplitude signals
connected to medium-voltage handling ports as far away from
the oscillator circuit as possible and do not allow such lines to
cross lines related to clock signals.
3. RES: Reset pin
Keep the line from the external reset circuit to the RES pin as short as possible.
Keep the length (L1, L2) of the lines from the capacitor (Cres) inserted between RES and V
SS
as short as possible.
4. TEST: Test pin
Keep the line that connects the TEST pin to V
SS
as short as possible.
Take the line that connects the TEST pin to V
SS
from a location as close to the V
SS
pin as possible.
