Test register
| RESERVED | Reserved |
| BASIC | Basic mode 0 (BASIC_MODE_DISABLED_): Basic mode disabled. 1 (TXRX): IF1 registers used as TX buffer, IF2 registers used as RX buffer. |
| SILENT | Silent mode 0 (NORMAL_OPERATION_): Normal operation. 1 (SILENT): The module is in silent mode. |
| LBACK | Loop back mode 0 (DISABLED): Loop back mode is disabled. 1 (ENABLED): Loop back mode is enabled. |
| TX | Control of CAN_TXD pins 0 (LEVEL): Level at the CAN_TXD pin is controlled by the CAN controller. This is the value at reset. 1 (TXD): The sample point can be monitored at the CAN_TXD pin. 2 (LOW): CAN_TXD pin is driven LOW/dominant. 3 (HIGH): CAN_TXD pin is driven HIGH/recessive. |
| RX | Monitors the actual value of the CAN_RXD pin. 0 (RECESSIVE): The CAN bus is recessive (CAN_RXD = 1). 1 (DORMANT): The CAN bus is dominant (CAN_RXD = 0). |
