but only one is performed at a given time as described ahead. The move-in starts only
when the message held by the Rx SMB has a corresponding matching winner (see
Section "Matching Process") and all of the following conditions are true:
The term pending move-in is used throughout the document and stands for a move-to-be
that still does not satisfy all of the aforementioned conditions.
The move-in is cancelled and the Rx SMB is able to receive another message if any of
the following conditions is satisfied:
Note that the pending move-in is not cancelled if the module enters Freeze or Low Power
Mode. It only stays on hold waiting for exiting Freeze and Low Pwer Mode and to be
unlocked. If an MB is unlocked during Freeze Mode, the move-in happens immediately.
The move-in process is the execution by the FlexCAN of the following steps:

1. if the message is destined to the Rx FIFO, push IDHIT into the RXFIR FIFO;
2. reads the words DATA0-3 and DATA4-7 from the Rx SMB;
3. writes it in the words DATA0-3 and DATA4-7 of the Rx Mailbox;
4. reads the words Control/Status and ID from the Rx SMB;
