Baud rate =
(BRP + 1) x (3 + TSEG1 + TSEG2)
TSEG2 ≥ SJW
Recommended:
TSEG1 > TSEG2
TSEG1 + TSEG2 ≥ 5
The following table lists the values of BRP, SJW, TSEG1, and TSEG2 for the
standard CAN baud rates that can be selected with the DIP-switches.

Meaning
BRP value
The Baud Rate Prescaler value determines the length
of the time quanta within one bit time.
SJW value
The (Re)Synchronisation Jump Width defines the
maximum number of time quanta a bit time may be
shortened or lengthened by one resynchronisation.
TSEG1 value
TSEG1 is the time segment within a bit time before the
sample point.
TSEG2 value
TSEG2 is the time segment within a bit time after the
sample point.
