The user can round to the closest minute, by setting the ROUND_30S register bit. TC values are set to the
closest minute value at the next second. The ROUND_30S bit is automatically cleared when the rounding time is
performed.
Example:
• If current time is 10H59M45S, a round operation changes time to 11H00M00S.
• if current time is 10H59M29S, a round operation changes time to 10H59M00S.
GENERAL REGISTERS
Software can access the RTC_STATUS_REG and RTC_CTRL_REG registers at any time (except for the
RTC_CTRL_REG[5] bit, which must be changed only when the RTC is stopped).
COMPENSATION REGISTERS
The RTC_COMP_MSB_REG and RTC_COMP_LSB_REG registers must respect the available access period.
These registers must be updated before each compensation process. For example, software can load the
compensation value into these registers after each hour event, during an available access period.
