Access Type:
• MDLC: Mailbox Data Length Code
• MRTR: Mailbox Remote Transmission Request
Consumer situations can be handled automatically by setting the mailbox object type in Consumer. This requires only one
mailbox.
It can also be handled using two mailboxes, one in reception, the other in transmission. The MRTR and the MTCR bits
must be set in the same time.
