The realtime clock (RTC) is a timer used to count time ranging from a second to a week. Figure
11.1 shows the block diagram of the RTC.
11.1
• Counts seconds, minutes, hours, and day-of-week
• Start/stop function
• Reset function
• Readable/writable counter of seconds, minutes, hours, and day-of-week with BCD codes
• Periodic (seconds, minutes, hours, days, and weeks) interrupts
• 8-bit free running counter
• Selection of clock source
• 8-bit bus (3 cycle access timing) connected to the external bus
RTC register is allocated to a part of area 7 of external address (H'FFFF48 to H'FFFF4F)
