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 (i.e.: 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.
