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 20-4.
When designing the board, place the crystal resonator and its load capacitors as close as possible to the XTAL and
EXTAL pins.
20.3.2
Circuit Configuration: An external clock signal can be input as shown in the examples in figure 20-5. If the XTAL pin is
left open, make sure that stray capacitance is no more than 10 pF.
In example (b) in fugure 20-5, make sure that the external clock is held high in standby mode.
External Clock: The external clock signal should have the same frequency as the system clock (ø).
