Rs max (Ω)
Co (pF)
Clock-Halving Version: Use a crystal resonator with a frequency equal to twice the system clock
frequency (ø).
1:1 Version: Use a crystal resonator with a frequency equal to the system clock frequency (ø).
Notes 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 16-4.
When the board is designed, the crystal resonator and its load capacitors should be placed as close
as possible to the XTAL and EXTAL pins.
