• SYNC_SEG: This segment has a fixed length of one time quantum. Signal edges are
• Time Segment 1: This segment includes the Propagation Segment and the Phase Segment
• Time Segment 2: This segment represents the Phase Segment 2 of the CAN standard.
Transmit Point
expected to happen within this section
1 of the CAN standard. It can be programmed by setting the PROPSEG and the PSEG1
fields of the CTRL Register so that their sum (plus 2) is in the range of 4 to 16 time
quanta
It can be programmed by setting the PSEG2 field of the CTRL Register (plus 1) to be
2 to 8 time quanta long

System expects transitions to occur on the bus during this period.
A node in transmit mode transfers a new value to the CAN bus at this point.
A node samples the bus at this point. If the three samples per bit option is selected, then this point
marks the position of the third sample.
