Section 23 Clock Pulse Generator
23.3.2
Circuit Configuration: An external clock signal can be input as shown in the examples in figure
23.5. 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, subactive mode,
subsleep mode, and watch mode.
External Clock: The external clock signal should have the same frequency as the system clock
( ).
Table 23.4 and figure 23.6 show the input conditions for the external clock.
