| DATA_B | Access data bytes 4-7 0 (UNCHANGED): Unchanged. Data bytes 4-7 unchanged. 1 (TRANSFER): Transfer. Transfer data bytes 4-7 to message object. |
| DATA_A | Access data bytes 0-3 0 (UNCHANGED): Unchanged. Data bytes 0-3 unchanged. 1 (TRANSFER): Transfer. Transfer data bytes 0-3 to message object. |
| TXRQST | Access transmission request bit 0 (NO_TRANSMISSION_REQU): No transmission request. TXRQSRT bit unchanged in IF1/2_MCTRL. If a transmission is requested by programming this bit, the TXRQST bit in the CANIFn_MCTRL register is ignored. 1 (REQUEST_A_TRANSMISSI): Request a transmission. Set the TXRQST bit IF1/2_MCTRL. |
