36.8.10 CAN Transfer Command Register
Name: CAN_TCR
Address: 0xFFFAC024
Access: Write-only
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.
When several mailboxes are requested to be transmitted simultaneously, they are transmitted in turn, starting with the
mailbox 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.
