1) Only valid after at least four recessive to dominant edges at TxD when entering the Normal Operation mode.
2) Only valid before four recessive to dominant edges at TxD when entering the Normal Operation mode.
3) Only valid before four recessive to dominant edges at TxD when entering the Normal Operation mode.
4) Power-Up flag only available, if V_CC and V_IO are active. Power-Up flag will be cleared when entering Normal Operation
mode.
5) Valid after a transition from Normal Operation mode.
6) Only valid if V_CC and V_IO are active.
