CHAPTER 12 REAL-TIME COUNTER
12.1 Functions
The real-time counter (RTC) has the following features.
• Counting up to 99 years using year, month, day-of-week, day, hour, minute, and second sub-counters provided
• Year, month, day-of-week, day, hour, minute, and second counter display using BCD codes
Note 1
• Alarm interrupt function
• Constant-period interrupt function (period: 1 month to 0.5 second)
• Interval interrupt function (period: 1.95 ms to 125 ms)
• Pin output function of 1 Hz
• Pin output function of 32.768 kHz
• Pin output function of 512 Hz or 16.384 kHz
• Watch error correction function
• Subclock operation or main clock operation
Note 2
selectable
Notes 1. A BCD (binary coded decimal) code expresses each digit of a decimal number in 4-bit binary format.
2. Use the baud rate generator dedicated to the real-time counter to divide the main clock frequency to
32.768 kHz for use.
