Real-time Clock (RTC) and Backup Battery
The EM2001 features an onboard real-time clock (RTC). As a source of backup power, the EM2001 relies on an onboard coin battery. Your Tibbo BASIC/C application can access the RTC through the RTC (rtc.) object, which is documented in the TIDE, TiOS, Tibbo BASIC, and Tibbo C Manual.
