It is used to compensate for signal delays across the network. Programming of the Sample Point allows optimizing the Bit Timing: This results in a prescaler divider up to But all registers are 32bit, with the highest 16 bits unused. The PIC32 family’s bit rate prescaler is only programmable between 1 to This results in larger values for TSEG.

Information Processing Time is less than or equal to 2 Time Quanta long. It is also used to compensate edge phase errors and may be shortened during resynchronization.
CAN: Add Flexcan CAN controller driver 
Two different sources show two different results. This makes code migration a relatively easy task, more so with code written in C language.
But some chips exist to substitute it. The bit timing pre-scaler is 10 bit wide and can divide by 1 to Flexcaj CAN controllers might allow other ranges.
Programming of the Sample Point allows optimizing the Bit Timing: A table can be requested by passing parameters on the http request line like http: It is used to compensate for edge phase errors and may be lengthened during resynchronization.
CNF1 controls the bit rate prescaler and the sync jump with. If a value is entered, it is only copied to the appropriate register. The value is currently not used in all calculations, please look at the values used below the bit timing table. The SJW ist not yet considered by the tool.
There is currently an issue for the high speed controllers in generating low CAN bit rates. Typical clock input frequency is 20Mhz. The table will be calculated for all CANopen defined bit rates.
It is used to synchronize the various bus nodes. The following is copied fom the manual chapter ” 1.
Add Support for Freescale FlexCAN CAN controller
BCR2 contains the bit pre-scaler in the lowest 8 bits. Prescaler value is 7 bit, 1 to If you find bugs freexcale this service, please inform Me. Up to three CAN modules are on chip. The CAN bit time may be programed in the range of 4 to 81 time quanta.
An explanation is given after the table if calculation was called.

By providing the input clock frequency feed into the Freescape clock Pre-scaler, the desired Sample Point location and selecting the CAN familythis page calculates possible register values to program CAN controllers for typical bit rates.

The Fast Baud Rate Prescaler has valid values from 0 to But all registers are 32bit, with the highest 16 bits unused. Intel The old Intel is not any more manufactured by Intel. Select this type for calculation of the register values. The document “CAN Bus1.
