Bit Timing

Table 538. Bit Timing Property

Data type	Permissions	Write while stopped?	Write while running?
	Write	Yes	No

Each CAN baud rate corresponds to multiple values for two Bit Timing Registers (BTR). The bit fields in these registers are consistent across almost all CAN controllers. This property specifies the baud rate as values for the Bit Timing Registers. The least significant byte is BTR0, and the most significant byte is BTR1.

The default value for this property comes from Module Configuration. The Baud Rate property is converted to commonly used BTR values, or you can specify BTR values directly in the CAN Advanced Port Configuration dialog.
