7.2.2
An external clock signal can be input at the EXTAL pin as shown in figure 7.4. The XTAL pin
should be left open. The frequency must be equal to the system clock (CK) frequency. The
specifications for the waveform of the external clock input are given below. Make the external
clock frequency the same as the system clock (CK).
