CAN232 FD User Manual
4.8 config can FDexpert
The
can FDexpert
level contains the fine tune parameters for CAN FD bit timing and sampling during the
data phase.
4.8.1 FDbaud <value>
Sets the baud rate to be used during the data phase of CAN FD communication when bit rate switching
(BRS) is enabled. This is the same setting as described for the previous
config can
level.
4.8.2 FDsample point <value>
Sets the sample point during the total bit time of the data phase as a percentage which dictates when the
CAN signal is sampled at each data bit.
4.8.3 FDclkdiv <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
32
will be
accepted. The FDbaud rate and other FDexpert settings will be automatically adjusted accordingly when this
parameter is changed.
The CAN controller uses a 16 MHz internal clock for baud rate generation.
4.8.4 FDtseg1 <value>
Sets the time segment 1 for the total bit time in the data phase which is the number of clock cycles before
the sample point. This value is automatically determined by the device based on FDbaud rate, FDclkdiv and
FDsample point. It does not normally need to be adjusted. Any value from
1
to
32
will be accepted. The
FDbaud rate, FDsample point and other FDexpert settings will be automatically adjusted accordingly when
this parameter is changed.
4.8.5 FDtseg2 <value>
Sets the time segment 2 for the total bit time in the data phase 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
16
will be accepted. The FDbaud rate,
FDsample point, FDsjw and other FDexpert settings will be automatically adjusted accordingly when this
parameter is changed.
