Table 24.3 Crystal Resonator Parameters
Note on Board Design
When a crystal resonator is connected, the following points should be noted.
Other signal lines should be routed away from the oscillator circuit to prevent induction from
interfering with correct oscillation. See figure 24.4.
When designing the board, place the crystal resonator and its load capacitors as close as possible
to the XTAL and EXTAL pins.
