Low power real-time clock
The real-time clock (RTC) is an independent binary coded decimal (BCD) timer/counter.
Six byte locations contain the second, minute, hour (12/24 hour), week day, date, month,
year, in BCD (binary coded decimal) format. Correction for 28, 29 (leap year), 30, and 31
day months are made automatically.
It provides a programmable alarm and programmable periodic interrupts with wakeup from
Halt capability.

OSC32_IN
Periodic wakeup time using the 32.768 kHz LSE with the lowest resolution (of 61 µs) is
from min. 122 µs to max. 3.9 s. With a different resolution, the wakeup time can reach
36 hours
Periodic alarms based on the calendar can also be generated from every second to
every year
