Notes: * After exiting hardware standby mode, this LSI enters the Power-On Reset state by the
RESET pin.
*1. Can be written to when MCR15 = MCR = 1 (Test Mode).
*2. Only allows writing a 1 to the Mailbox designated for transmission.
*3. Cannot be modified.
*4. The Message Control, Message Data, Timestamp and LAFM fields can only be
accessed with 16 bits, whereas the Message Data area can be accessed with 16 bits or
8 bits. Also, unused parts of Mailboxes must be initialized during the configuration to
their inactive state as they are configured of RAM.
*5. Unused Mailboxes can be used as memory. However, it is important in such case to
disable the related mailbox (setting MBC to B’111) in order to avoid that the mailbox
joins the search for a matching identifier during the reception of messages, and even
store a wrong message in the worst case.
