Access Type:
• MTIMEMARK: Mailbox Timemark
This field is active in Time Triggered Mode. Transmit operations are allowed when the internal timer counter reaches the
Mailbox Timemark. See
In Timestamp Mode, MTIMEMARK is set to 0.
• PRIOR: Mailbox Priority
This field has no effect in receive and receive with overwrite modes. In these modes, the mailbox with the lowest number is
serviced first.
When several mailboxes try to transmit a message at the same time, the mailbox with the highest priority is serviced first. If
several mailboxes have the same priority, the mailbox with the lowest number is serviced first (i.e., MBx0 is serviced before
MBx 15 if they have the same priority).
• MOT: Mailbox Object Type
This field allows the user to define the type of the mailbox. All mailboxes are independently configurable. Five different
types are possible for each mailbox:

Mailbox is disabled. This prevents receiving or transmitting any messages
with this mailbox.
Reception Mailbox. Mailbox is configured for reception. If a message is
received while the mailbox data register is full, it is discarded.
Reception mailbox with overwrite. Mailbox is configured for reception. If a
message is received while the mailbox is full, it overwrites the previous
message.
Transmit mailbox. Mailbox is configured for transmission.
Consumer Mailbox. Mailbox is configured in reception but behaves as a
Transmit Mailbox, i.e., it sends a remote frame and waits for an answer.
Producer Mailbox. Mailbox is configured in transmission but also behaves
like a reception mailbox, i.e., it waits to receive a Remote Frame before
sending its contents.
