Section 23 Clock Pulse Generator
23.9.2
When designing the board, place the crystal resonator and its load capacitors as close as possible
to the EXTAL, XTAL, OSC1, and OSC2 pins. Make wires as short as possible. Other signal lines
should be routed away from the oscillator circuit, as shown in figure 23.11. This is to prevent
induction from interfering with correct oscillation.
