Update APB_TIME_MANAGEMENT :...
Update APB_TIME_MANAGEMENT : If LFR is desynchronized, the LFR is resynchronized only if there is a tick (or soft_tick) and a new TCU The TCU is a vector of 31 bits (30 downto 0). Now, there is a ctrl bit to soft reset the apb_time_management. After a reset (and a soft reset), the APB_TM is desynchronized and the CT value is 0x80000000.
