Because of the uncertainty of the time when the time counter increments, it
is recommended that the target time register be written with a value that is
at least two counts greater than the current value of the RTC_ATC register.
The number, in seconds, to generate the HIB_MODE signal.
When RTC_TTR = 0x0000_0000, entering Hibernation or Deep Sleep mode is not possible.
If it is desired to use one of the wakeup sources to wakeup
(RTC_KAR)”), then write RTC_TTR to 0xFFFF_FFFF. This allows to assert the HIB_MODE signal and to enter
Deep Sleep mode, when non of the external wake up sources (GPIO[00:03] or CAN[1:2]_RX) prevent this.
