13.5.3 Transmit Abort Function
The transmit abort function is used to cancel a transmit request that has once been set. This is
accomplished by writing H'0F to the CAN Message Slot Control Register for the slot whose transmit
request is to be canceled.
When transmit abort is accepted, the CAN module clears the CAN Message Slot Control Register
TRSTAT (transmit/receive status) bit to 0, with the message slot thereby allowed for write.
The following lists the conditions under which transmit abort is accepted.
[Conditions]
•
When the target message is waiting for transmission
•
When a CAN bus error occurs during transmission
•
When the CAN module loses in bus arbitration
