• MRDY: Mailbox Ready
An interrupt is triggered when MRDY is set.
0 = Mailbox data registers can not be read/written by the software application. CAN_MDx are locked by the CAN_MDx.
1 = Mailbox data registers can be read/written by the software application.
This flag is cleared by writing to CAN_MCRx register.
• MMI: Mailbox Message Ignored
0 = No message has been ignored during the previous transfer
1 = At least one message has been ignored during the previous transfer
Cleared by reading the CAN_MSRx register.

Description
Description
Set when at least two messages intended for the mailbox have been sent. The first one is available in the
mailbox data register. Others have been ignored. A mailbox with a lower priority may have accepted the
message.
Set when at least two messages intended for the mailbox have been sent. The last one is available in the
mailbox data register. Previous ones have been lost.
Reserved
A remote frame has been sent by the mailbox but several messages have been received. The first one is
available in the mailbox data register. Others have been ignored. Another mailbox with a lower priority may
have accepted the message.
A remote frame has been received, but no data are available to be sent.
