Description
Cancel the transmit wait message in the
corresponding mailboxes from 16 to 31. When
TXCRn (n = 16 to 31) is set to 1, the transmit wait
message in mailbox n is canceled.
[Clearing condition]
•
To clear the corresponding bit in TXPR, 1 must be
written to the corresponding bit TXCR. When
cancellation has succeeded, the HCAN2 clears the
corresponding TXPR/TXCR bits, and sets the
corresponding ABACK bit. However, once a mailbox
has started transmission, it cannot be canceled by
this bit.
Notes: 1. 1 can be written only when the mailbox is
Completion of TXPR clearing (when transmit
message is canceled normally), or normal end
process is carried out (when transmit message is
being transmitted, thereby unable to be canceled)
2. Restrictions apply to the use of the

mailbox 31 for transmission. Carefully
