Appendix C. CAN Baud Rate Calculating

This section will describe how to calculate CAN baud rate for I-7530 series module, not including

tM-7530, tM-7530A, and tM-7565, via using old version utility, CAN converter utility, to fill these

parameters.

The users can use user-defined CAN Baud rate by setting CAN Converter utility. There are four

parameters for this function, please refer the below setting window.

1. Clock Mode:

This parameter is means MCU clock. If the CAN Baud rate is less then 12k, this parameter

value is "0", others are "1".

2. Bit Timing 1:

This parameter is MCU's bit timing register 1, please refer to the next page "Table: Bit Timing

3. Bit Timing 2:

This parameter is MCU's bit timing register 2, please refer to the next page "Table: Bit Timing

4. Bit Timing 3:

This parameter is MCU's bit timing register 3, please refer to the next page "Table: Bit Timing

How to fill those parameter:

The Bit Timing register includes six kinds of parameter, BRP, SJW, PRS, PHS2, PHS1, and SMP.

Please refer to the following table.
