The function switching HSCLK to LSCLK is not available on ML610Q415.
If the system clock is switched from a low-speed clock to a high-speed clock before the high-speed clock
(HSCLK) starts oscillation, the CPU becomes inactive until HSCLK starts clock supply to the peripheral circuits.

500kHz RC osciilation mode can not be used.
Remain using the low-speed clock (LSCLK).
