(3) The rule of user-defined CAN baud rate setting in the SJA1000
CAN devices for communication compatible with I-7565-H1/H2:
If users use I-7565-H1/H2 to communicate with SJA1000 CAN
devices and CAN baud rate is user-defined CAN baud rate. Then in
SJA1000 CAN devices, users need to choose a set of proper CAN
parameter (BTR0 & BTR1) for communication compatible with I-
7565-H1/H2 and the rule is as follows:
(1) The “Samples” value is 1.
(1) The “SJW” value is as small as possible. (1 is the best).
(2) The “Tseg2” value is as small as possible. (1 is the best)
(3) The “Tseg1” value is as large as possible.
According to the above four rules, users can choose the proper
BTR0 and BTR0. For example, if uses want to use the CAN baud rate
is 83.333 Kbps, according to the above rules, users should choose
BTR0=05 and BTR1=1C for the CAN parameter of SJA1000 CAN
devices like Figure 6-3.
