Table 23.4 External Clock Input Conditions (Duty Adjustment Circuit Unused) (5)
Note: When a duty adjustment circuit is not used, maximum operating frequency is lowered
23.2.3
When two or more external clocks (e.g.:10 MHz and 2 MHz) are used as the system clock, input
clock should be switched in software standby mode.
An example of external clock switching circuit is shown in figure 23.6. An example of external
clock switching timing is shown in figure 23.7.
