Function
Transmit Status 1.
There is no transmission from Tx Buffer 1.
The CAN Controller is transmitting a message from Tx Buffer 1.
Error Status. This bit is identical to the ES bit in the CANxGSR.
Bus Status. This bit is identical to the BS bit in the CANxGSR.
Receive Buffer Status. This bit is identical to the RBS bit in the CANxGSR.
Data Overrun Status. This bit is identical to the DOS bit in the CANxGSR.
Transmit Buffer Status 2.
Software cannot access the Tx Buffer 2 nor write to the corresponding
CANxTFI, CANxTID, CANxTDA, and CANxTDB registers because a
message is either waiting for transmission or is in transmitting process.
Software may write a message into the Transmit Buffer 2 and its CANxTFI,
CANxTID, CANxTDA, and CANxTDB registers.
Transmission Complete Status.
The previously requested transmission for Tx Buffer 2 has been successfully
completed.
Receive Status. This bit is identical to the RS bit in the GSR.
Transmit Status 2.
There is no transmission from Tx Buffer 2.
The CAN Controller is transmitting a message from Tx Buffer 2.
Error Status. This bit is identical to the ES bit in the CANxGSR.
Bus Status. This bit is identical to the BS bit in the CANxGSR.
Receive Buffer Status. This bit is identical to the RBS bit in the CANxGSR.
Data Overrun Status. This bit is identical to the DOS bit in the CANxGSR.
Transmit Buffer Status 3.
Software cannot access the Tx Buffer 3 nor write to the corresponding
CANxTFI, CANxTID, CANxTDA, and CANxTDB registers because a
message is either waiting for transmission or is in transmitting process.
Software may write a message into the Transmit Buffer 3 and its CANxTFI,
CANxTID, CANxTDA, and CANxTDB registers.
Transmission Complete Status.
The previously requested transmission for Tx Buffer 3 has been successfully
completed.
Receive Status. This bit is identical to the RS bit in the GSR.
Transmit Status 3.
There is no transmission from Tx Buffer 3.
The CAN Controller is transmitting a message from Tx Buffer 3.
