The signal input to the main clock oscillator is oscillated by a ceramic or crystal resonator connected to the X1 and
An external clock signal can also be input to the main clock oscillator.
Figure 6-2 shows an example of the circuit connected to the main clock oscillator.
The signal input to the subclock oscillator is oscillated by a crystal resonator connected to the XT1 and XT2 pins.
Figure 6-3 shows an example of the circuit connected to the subclock oscillator.
