• Time Segment 2: This segment represents the Phase Segment 2 of the CAN standard. It can
fields of the CANCTRLn register so that their sum (plus 2) is in the range of 4 to 16 time
quanta
be programmed by setting the PSEG2 field of the CANCTRLn register (plus 1) to be 2 to
8 time quanta long
gives an overview of the CAN compliant segment settings and the related parameter
It is the user’s responsibility to ensure the bit time settings are in
compliance with the CAN standard. For bit time calculations, use an
IPT (Information Processing Time) of 2, which is the value
implemented in the FlexCAN module

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.
