11. REAL-TIME COUNTER
In the V850ES/Jx3-E, one channel of real-time counter is provided.
The real-time counter has the following features.
• It has counters for year, month, week, day, hours, minutes and seconds, and it can count up to 99 years.
• The year, month, week, day, hour, minute and second counters show the count in BCD code^{Note 1}.
• Alarm interrupt function
• Fixed-cycle interrupt function (cycle: 1 month to 0.5 seconds)
• Interval interrupt function (cycle: 1.95 to 125 ms)
• 1 Hz pin output
• 32.768 kHz pin output
• 512 Hz or 16.384 kHz pin output
• Watch error correction function
• Subclock operation or main clock operation^{Note 2} selectable
Notes 1. BCD (binary-coded decimal) code is the code that represents each digit of a decimal number in 4-bit
binary numerals.
2. The main clock can be divided into 32.768 kHz fBRG with the baud rate generator dedicated to the real-time
counter.
