MSCAN
The synchronization jump width
parameter.
The above parameters are set by programming the MSCAN Bus Timing Registers (CANBTR0,
CANBTR1) (see
“MSCAN Bus Timing Register 1
Table 22-32
22.4.6
The MSCAN generates an internal time stamp when a valid frame is received or transmitted and the TIME
bit is enabled. Because the CAN specification defines a frame to be valid if no errors occur before the End
of Frame (EOF) field is transmitted successfully, the actual value of an internal timer is written at EOF to
the appropriate time stamp position within the transmit buffer. For receive frames, the time stamp is written
to the receive buffer.

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 in receive mode samples the bus at this point. If the three samples per bit option
is selected, this point marks the position of the third sample.
