16.1
This LSI has a realtime clock (RTC) with its own 32.768-kHz crystal oscillation circuit.
16.1.1
The RTC has the following features:
• Clock and calendar functions (BCD display): Seconds, minutes, hours, date, day of the week,
• 1 to 64-Hz timer (binary display)
• Start/stop function
• 30-second adjustment
• Alarm interrupt:
• Periodic interrupts:
• Carry interrupt: A carry interrupt indicates when a carry occurs during a counter read
• Automatic leap year correction
month, and year
Frame comparisons of seconds, minutes, hours, date, day of the week, and month can be
selected for the alarm interrupt condition
The interrupt cycle can be selected from 1/256 second, 1/64 second, 1/16 second, 1/4 second,
1/2 second, 1 second, or 2 seconds
