Message interface command mask (write direction)
| DATA_B | Access data bytes 4-7 0 (DATA_BYTES_4_7_UNCHA): data bytes 4-7 unchanged. 1 (TRANSFER_DATA_BYTES_): Transfer data bytes 4-7 to message object. |
| DATA_A | Access data bytes 0-3 0 (DATA_BYTES_0_3_UNCHA): data bytes 0-3 unchanged. 1 (TRANSFER_DATA_BYTES_): 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. |
| CLRINTPND | This bit is ignored in the write direction. |
| CTRL | Access control bits 0 (CONTROL_BITS_UNCHANG): Control bits unchanged. 1 (TRANSFER_CONTROL_BIT): Transfer control bits to message object |
| ARB | Access arbitration bits 0 (ARBITRATION_BITS_UNC): Arbitration bits unchanged. 1 (TRANSFER_IDENTIFIER): Transfer Identifier, DIR, XTD, and MSGVAL bits to message object. |
| MASK | Access mask bits 0 (MASK_BITS_UNCHANGED_): Mask bits unchanged. 1 (TRANSFER_IDENTIFIER_): Transfer Identifier MASK + MDIR + MXTD to message object. |
| WR_RD | Write transfer Transfer data from the selected message buffer registers to the message object addressed by the command request register CANIFn_CMDREQ. |
| RESERVED | reserved |
