Control 1 register
| PROPSEG | Propagation Segment |
| LOM | Listen-Only Mode 0 (LOM_0): Listen-Only mode is deactivated. 1 (LOM_1): FlexCAN module operates in Listen-Only mode. |
| LBUF | Lowest Buffer Transmitted First 0 (LBUF_0): Buffer with highest priority is transmitted first. 1 (LBUF_1): Lowest number buffer is transmitted first. |
| TSYN | Timer Sync 0 (TSYN_0): Timer Sync feature disabled 1 (TSYN_1): Timer Sync feature enabled |
| BOFFREC | Bus Off Recovery 0 (BOFFREC_0): Automatic recovering from Bus Off state enabled. 1 (BOFFREC_1): Automatic recovering from Bus Off state disabled. |
| SMP | CAN Bit Sampling 0 (SMP_0): Just one sample is used to determine the bit value. 1 (SMP_1): Three samples are used to determine the value of the received bit: the regular one (sample point) and 2 preceding samples; a majority rule is used. |
| RWRNMSK | Rx Warning Interrupt Mask 0 (RWRNMSK_0): Rx Warning Interrupt disabled. 1 (RWRNMSK_1): Rx Warning Interrupt enabled. |
| TWRNMSK | Tx Warning Interrupt Mask 0 (TWRNMSK_0): Tx Warning Interrupt disabled. 1 (TWRNMSK_1): Tx Warning Interrupt enabled. |
| LPB | Loop Back Mode 0 (LPB_0): Loop Back disabled. 1 (LPB_1): Loop Back enabled. |
| CLKSRC | CAN Engine Clock Source 0 (CLKSRC_0): The CAN engine clock source is the oscillator clock. Under this condition, the oscillator clock frequency must be lower than the bus clock. 1 (CLKSRC_1): The CAN engine clock source is the peripheral clock. |
| ERRMSK | Error Interrupt Mask 0 (ERRMSK_0): Error interrupt disabled. 1 (ERRMSK_1): Error interrupt enabled. |
| BOFFMSK | Bus Off Interrupt Mask 0 (BOFFMSK_0): Bus Off interrupt disabled. 1 (BOFFMSK_1): Bus Off interrupt enabled. |
