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.

bypass). Refer to Section HSE clock in the STM8L15x and STM8L16x reference manual (RM0031).
bypass). Refer to Section LSE clock in the STM8L15x and STM8L16x reference manual (RM0031).
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
