For example, display the current year:
RTC_Initialize();
u8 year = RTC_GetYear();
Print_DrawFormat("This year: %i", 1980 + year);
Save data to CMOS memory:
u8 saveData[6]; saveData[0] = 0xFF; saveData[1] = 100; saveData[2] = 0; RTC_SaveData(saveData);
The MSX2 real-time clock is a Ricoh RP-5C01. For more information about this device:
