7.9 Precautions
• The OSC3 oscillation start time depends on the oscillator and externally connected components. The time should
be set with an adequate OSC3 oscillation stabilization wait time. Refer to the typical oscillation start times speci-
fied in “24 Electrical Characteristics.”
• Switching the system clock from OSC3 to OSC1 immediately after starting OSC1 oscillation will stop the sys-
tem clock until the OSC1 clock starts up (for the OSC1 clock 256-cycle period).
• The OSC3 oscillator circuit cannot be stopped if the OSC3 clock is being used as the system clock.
• The OSC1 oscillator circuit cannot be stopped if the OSC1 clock is being used as the system clock.
• Since the FOUT3/FOUT1 signal is asynchronized with FOUT3E/FOUT1E writing, switching output on or off
will generate certain hazards.
