Description

Control 1 register

Fields

PROPSEG

Propagation Segment

LOM

Listen-Only Mode

0 (0): Listen-Only mode is deactivated.

1 (1): FlexCAN module operates in Listen-Only mode.

LBUF

Lowest Buffer Transmitted First

0 (0): Buffer with highest priority is transmitted first.

1 (1): Lowest number buffer is transmitted first.

TSYN

Timer Sync

0 (0): Timer Sync feature disabled

1 (1): Timer Sync feature enabled

BOFFREC

Bus Off Recovery

0 (0): Automatic recovering from Bus Off state enabled, according to CAN Spec 2.0 part B.

1 (1): Automatic recovering from Bus Off state disabled.

SMP

CAN Bit Sampling

0 (0): Just one sample is used to determine the bit value.

1 (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 (0): Rx Warning Interrupt disabled.

1 (1): Rx Warning Interrupt enabled.

TWRNMSK

Tx Warning Interrupt Mask

0 (0): Tx Warning Interrupt disabled.

1 (1): Tx Warning Interrupt enabled.

LPB

Loop Back Mode

0 (0): Loop Back disabled.

1 (1): Loop Back enabled.

CLKSRC

CAN Engine Clock Source

0 (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 (1): The CAN engine clock source is the peripheral clock.

ERRMSK

Error Mask

0 (0): Error interrupt disabled.

1 (1): Error interrupt enabled.

BOFFMSK

Bus Off Mask

0 (0): Bus Off interrupt disabled.

1 (1): Bus Off interrupt enabled.

PSEG2

Phase Segment 2

PSEG1

Phase Segment 1

RJW

Resync Jump Width

PRESDIV
