22B.3.2 External Clock Input
Circuit Configuration
An external clock signal can be input as shown in the examples in figure 22B-6. If the XTAL pin
is left open, make sure that stray capacitance is no more than 10 pF.
In example (b), make sure that the external clock is held high in standby mode.
In this case, the input clock frequency should be between 4 MHz and 5 MHz.
