... HF clock depends on the quality of the 32.768 kHz internally generated clock; the low-frequency (LF) Oscillator System is described later in this document. When the Real-Time Clock module of the SH3001 is used for high-accuracy timekeeping, an external 32.768 kHz crystal used as a reference for RTC provides excellent accuracy and stability for the Clock Management System ...

... They are the Real-Time Clock and the Periodic Interrupt / Wakeup Timer. Both of these units as well as other functions of the SH3001 depend on the internal 32.768 kHz clock for accuracy. With one external component (a 32.768 kHz crystal), the SH3001 can provide a processor clock accuracy of ± ...
