Description
These bits set a transmit wait (CAN bus arbitration
wait) for the corresponding mailboxes 1 to 15.
When TXPRn (n = 1 to 15) is set to 1, the message
in mailbox n becomes the transmit wait state.
[Clearing conditions]
• Completion of message transmission
• Completion of transmission cancellation
Bit 8 is reserved. This bit is always read as 1 and
the write value should always be 1.
