Bits Field Name Description Type Reset
7 RTC_V_OPT RTC date / time register selection: RW 0
0: Read access directly to dynamic registers (SECONDS_REG,
MINUTES_REG, HOURS_REG, DAYS_REG, MONTHS_REG,
YEAR_REG, WEEKS_REG)
1: Read access to static shadowed registers: (see GET_TIME bit).
6 GET_TIME When writing a 1 into this register, the content of the dynamic registers RW 0
(SECONDS_REG, MINUTES_REG, HOURS_REG, DAYS_REG,
MONTHS_REG, YEAR_REG and WEEKS_REG) is transferred into
static shadowed registers. Each update of the shadowed registers needs
to be done by re-asserting GET_TIME bit to 1 (that is, reset it to 0 and
then re-write it to 1)
5 SET_32_COUNTER 0: No action RW 0
1: set the 32-kHz counter with COMP_REG value.
It must only be used when the RTC is frozen.
4 TEST_MODE 0: functional mode RW 0
1: test mode (Auto compensation is enable when the 32kHz counter
reaches at its end)
3 MODE_12_24 0: 24 hours mode RW 0
1: 12 hours mode (PM-AM mode)
It is possible to switch between the two modes at any time without
disturbed the RTC, read or write are always performed with the current
mode.
2 AUTO_COMP 0: No auto compensation RW 0
1: Auto compensation enabled
1 ROUND_30S 0: No update RW 0
1: When a one is written, the time is rounded to the closest minute.
This bit is a toggle bit, the micro-controller can only write one and RTC
clears it. If the micro-controller sets the ROUND_30S bit and then read it,
the micro-controller will read one until the rounded to the closet.
0 STOP_RTC 0: RTC is frozen RW 0
1: RTC is running
