equal to 0x0, it disturbs message transmits.

Preliminary
Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Receive Observation
Displays the value on the CANnRx pin.
Transmit Control
Overrides control of CANnTx pin.
Loopback Mode
0: Disabled.
1: Enabled.
Silent Mode
Do not transmit data; monitor the bus. Also known as Bus Monitor mode.
0: Disabled.
1: Enabled.
Basic Mode
0: Disabled.
