Notes on Board Design:
When generating clock pulses by connecting a crystal or ceramic
resonator, pay careful attention to the following points.
Avoid running signal lines close to the oscillator circuit, since the oscillator may be adversely
affected by induction currents. (See figure 4.5.)
The board should be designed so that the oscillator and load capacitors are located as close as
possible to pins OSC
1
and OSC
2
.
