Table 24.4 External Clock Output Stabilization Delay Time
Conditions: V
Note:
24.2
The duty correction circuit is valid when the oscillating frequency is 5 MHz or more. It corrects
the duty of a clock that is output from the oscillator, and generates the system clock ( ).
24.3
The medium-speed clock divider divides the system clock ( ), and generates /2, /4, /8, /16,
and /32 clocks.
