word Value Meaning
m+16 0000 ~ 0063 BRP value
The Baud Rate Prescaler value determines the length
of the time quanta within one bit time.
m+17 0000 ~ 0003 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.
m+18 0002 ~ 0015 TSEG1 value
TSEG1 is the time segment within a bit time before the
sample point.
m+19 0001 ~ 0007 TSEG2 value
TSEG2 is the time segment within a bit time after the
sample point.
8 000
Baud rate =
(BRP + 1) x (3 + TSEG1 + TSEG2)
[kbit/s]
Recommended:
TSEG2
≥
SJW
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.
