4.6.1
Figure 4.2 is an example of connecting the external clock input. When putting the XTAL pin in
open state, make sure the parasitic capacitance is less than or equal to 10 pF. To stably input the
external clock with enough PLL stabilizing time at power on or releasing the standby, wait longer
than the oscillation stabilizing time.
For details on input conditions of the external clock, see section 29.3.1, Clock Timing.
4.6.2
Place the crystal resonator and capacitors CL1 and CL2 as close to the XTAL and EXTAL pins as
possible. In addition, to minimize induction and thus obtain oscillation at the correct frequency,
the capacitors to be attached to the resonator must be grounded to the same ground. Do not bring
wiring patterns close to these components.
