2.4 Transmit Buffer Interrupt Processing
2.4.1 Transmit Complete Interrupt Processing
If the transmit complete interrupt is enabled, the CANm transmit interrupt is generated when the transmission is
completed. Whether to enable or disable the transmit complete interrupt can be set for each transmit buffer by the
TMIEp bit of the TMIECy register.
The CANm transmit interrupts share the following sources. When using multiple interrupt sources, determine the
sources within the interrupt as necessary.
The source of the CANm transmit interrupt can also be confirmed in the GTINTSTS0 register.
・CANm transmit complete interrupt
・CANm transmit abort interrupt
・CANm transmit/receive FIFO transmit complete interrupt
・CANm transmit queue interrupt
・CANm transmit history interrupt

2.4.2 Transmit Abort Complete Interrupt Processing
If the transmit abort complete interrupt is enabled, the CANm transmit interrupt is generated when the transmit abort
is completed. Whether to enable or disable the transmit abort complete interrupt can be set for each channel with the
TAIE bit of the CmCTR register. However, if the transmission is completed: There is an abort request (TMTRF [1: 0]
flag is "B'11"), the transmit abort complete interrupt is not generated and the transmit complete interrupt is generated.
The CANm transmit interrupts share the following sources. When using multiple interrupt sources, determine the
sources within the interrupt as necessary.
The sources of the CANm transmit interrupt can also be confirmed in the GTINTSTS0 register.
・CANm transmit complete interrupt
・CANm transmit abort interrupt
・CANm transmit/receive FIFO transmit complete interrupt
・CANm transmit queue interrupt
・CANm transmit history interrupt
