• MACR: Abort Request for Mailbox x
It is possible to set MACR field for several mailboxes in the same time, setting several bits to the CAN_ACR register.
• MTCR: Mailbox Transfer Command
This flag clears the MRDY and MABT flags in the CAN_MSRx register.
When several mailboxes are requested to be transmitted simultaneously, they are transmitted in turn. 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 will be serviced before MBx 15 if they have the same priority).
It is possible to set MTCR for several mailboxes at the same time by writing to the CAN_TCR register.
