accuracy of 6 MHz ±500 ppm or less when using the internal clock as the USB clock.
When using the external clock input by the UCLK pin, be sure to supply a clock with an
accuracy of 48 MHz ±500 ppm or less.
If the USB clock accuracy drops, the transmission/reception data cannot satisfy the USB
specification.
the above figure to avoid an adverse effect from wiring capacitance.
• Keep the wiring length as short as possible.
• Do not cross the wiring with the other signal lines.
• Do not route the wiring near a signal line through which a high fluctuating current flows.
• Always make the ground point of the oscillator capacitor the same potential as V
• Do not ground the capacitor to a ground pattern through which a high current flows.
• Do not fetch signals from the oscillator.
oscillation stabilization time has been secured by the program before switching back to the
main clock.
