RTC Registers Example (continued) Register Value HOURS_REG 0x90 DAYS_REG 0x05 MONTHS_REG 0x09 YEARS_REG 0x08 The user can round to the nearest minute, by setting the ROUND_30S register bit. TC values are set to the nearest 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. 6.9.2 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). 6.9.3 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.
