The X1 oscillator oscillates with a crystal resonator or ceramic resonator (1 to 20 MHz) connected to the X1 and X2
An external clock can also be input. In this case, input the clock signal to the EXCLK pin.
Figure 6-12 shows an example of the external circuit of the X1 oscillator.
Cautions are listed on the next page.
The XT1 oscillator
An external clock can also be input. In this case, input the clock signal to the EXCLKS pin.
Figure 6-13 shows an example of the external circuit of the XT1 oscillator.
