Name:
Access Type:
This register initializes several transfer requests at the same time.
• MBx: Transfer Request for Mailbox x
This flag clears the MRDY and MABT flags in the corresponding CAN_MSRx register.
When several mailboxes are requested to be transmitted simultaneously, they are transmitted in turn, starting with the mail-
box with the highest priority. If several mailboxes have the same priority, then the mailbox with the lowest number is sent
first (i.e., MB0 will be transferred before MB1).
• TIMRST: Timer Reset
Resets the internal timer counter. If the internal timer counter is frozen, this command automatically re-enables it. This
command is useful in Time Triggered mode.
