The realtime clock (RTC) is a timer used to count time ranging from a second to a week.
Interrupts can be generated ranging from 0.25 seconds 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 (0.25 seconds, 0.5 seconds, one second, minute, hour, day, and week) interrupts
• 8-bit free running counter
• Selection of clock source
• Use of module standby mode enables this module to be placed in standby mode independently
