CAN232 FD User Manual
4-31
4.7.1 baud <value>
Sets the baud rate to be used for classic CAN communication. This is the same setting as described for the
previous
config can
level.
4.7.2 sample point <value>
Sets the sample point during the total bit time as a percentage which dictates when the CAN signal is
sampled at each bit. This is the same setting as described for the previous
config can
level.
4.7.3 clkdiv <value>
Sets the clock divider for the CAN controller’s baud rate generator. This value is automatically determined
by the device based on baud rate and does not normally need to be adjusted. Any value from
1
to
48
will be
accepted. The baud rate and other expert settings will be automatically adjusted accordingly when this
parameter is changed.
The CAN controller uses a 16 MHz internal clock for baud rate generation.
4.7.4 tseg1 <value>
Sets the time segment 1 for the total bit time which is the number of clock cycles before the sample point.
This value is automatically determined by the device based on baud rate, clkdiv and sample point. It does
not normally need to be adjusted. Any value from
1
to
256
will be accepted. The baud rate, sample point and
other expert settings will be automatically adjusted accordingly when this parameter is changed.
4.7.5 tseg2 <value>
Sets the time segment 2 for the total bit time which is the number of clock cycles after the sample point.
This value is automatically determined by the device based on baud rate, clkdiv and sample point. It does
not normally need to be adjusted. Any value from
1
to
128
will be accepted. The baud rate, sample point,
sjw and other expert settings will be automatically adjusted accordingly when this parameter is changed.
4.7.6 sjw <value>
Sets the synchronization jump width (sjw) for the CAN receiver. This is the maximum number of Tq
adjustment the receiver can make to adjust for oscillator differences between CAN nodes. It does not
normally need to be adjusted. Any value from
1
to
tseg2
will be accepted.
