36.8.10 CAN Transfer Command Register
Name: CAN_TCR
Access Type: 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 register.
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.
