This LSI has a realtime clock (RTC) with its own 32.768-kHz crystal oscillator. A block diagram
of the RTC is shown in figure 13.1.
13.1
The RTC has following features:
Clock and calendar functions (BCD display): seconds, minutes, hours, date, day of the week,
month, and year
1-Hz to 64-Hz timer (binary display)
Start/stop function
30-second adjust function
Alarm interrupt: frame comparison of seconds, minutes, hours, date, day of the week, and
month can be used as conditions for the alarm interrupt
Cyclic interrupts: the interrupt cycle may be 1/256 second, 1/64 second, 1/16 second, 1/4
second, 1/2 second, 1 second, or 2 seconds
Carry interrupt: a carry interrupt indicates when a carry occurs during a counter read
Automatic leap year correction
