(1) Clock accuracy
(2) Stopping the USB clock
To operate the USB function controller, the internal clock (6 MHz external clock × internal clock multiplied by 8
= 48 MHz internal clock) or external clock (external clock input to EXCLK pin (f
the USB clock. When the internal clock is used as the USB clock, use a resonator with an accuracy of 6 MHz
±500 ppm (max.). When the external clock is used, apply a clock with an accuracy of 48 MHz ±500 ppm
(max.) to the EXCLK pin. If the USB clock accuracy drops, the transmission data cannot satisfy the USB rating.
When the main clock (f

UFCKMSK register to 1) first before stopping the main clock (f

Similarly, when an external clock whose signal is input from the EXCLK pin is selected as the USB function
controller clock, measures must be taken to prevent noise from being generated in the clock pulse by the
external circuit. If this is not feasible, then the USB function controller must be stopped first before stopping the
