How to set value for registers of MC 33665A CAN FD variant ? We have some develop files with NDA permmission ( including product data sheet ) , we konw the meaning of each value of registers by checking the data sheet. But there is no information about how to set the corresponding value .

If the value could be set by CAN FD communication ? Or it must be set via some source code ang programming files ?

Thanks a lot

Dear Longxuan,

the registers must be set via CAN interface. You need to use an CAN transceiver for both CAN to TPL transmission and for registers configuration. Please refer to Figure 50. The same way as the I2C registers, the other registers should be configured.

Commands with CADD=0 and DADD=1 provide access to the internal registers. Please refer to the Figure 3. in the MC33665A V3. datasheet.

Please refer to the section 5.1.1.

With Best Regards,

Jozef
