Freescale’s Scalable Controller Area Network (S12MSCANV3)
The synchronization jump width (see the Bosch CAN 2.0A/B specification for details) can be programmed
in a range of 1 to 4 time quanta by setting the SJW parameter.
The SYNC_SEG, TSEG1, TSEG2, and SJW parameters are set by programming the MSCAN bus timing
registers (CANBTR0, CANBTR1) (see
and

related parameter values.

11.4.4.1
The MSCAN module behaves as described within this specification in all normal system operating modes.
Write restrictions exist for some registers.

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