ML610400 series/ML610300 seriesThe item "Note" of "Clock Generation Circuit"of User's Manual describes that operation is not guaranteed if the low-speed clock is not supplied to this LSI. However, is it possible to operate the LSI with the 500 kHz RC oscillation alone when only the peripheral circuits that do not use 32.768 kHz are used?
Please be sure to supply the low-speed clock. If the 32.768 kHz low-speed clock is not supplied to this LSI, the low-speed oscillation stop detecting function to monitor the low-speed clock is activated to generate a reset.
