Hi,
I'am using the example "FLEXCAN" for the s32k144 board. For my purpose, I want to have as baud rate 50KSamples/second. From the theory I understood that, it is important to modify some fields of CTRL register for the desired baud rate. So, I want to know if it's correct this configuration for the baud rate equal to 50KSamples/seconds.
CAN_CTRL1_PRESDIV(49) (40MHz/(49+1)) = 800KHz
CAN_CTRL1_PSEG2(3) /* Configure for 50 KHz bit time */
CAN_CTRL1_PSEG1(3) /* Time quanta freq = 16 time quanta x 50 KHz bit time= 800KHz */
CAN_CTRL1_PROPSEG(6) /* PRESDIV+1 = Fclksrc/Ftq = 8 MHz/8 MHz = 1 */
CAN_CTRL1_RJW(3) /* so PRESDIV = 0 */
Is this configuration correct for the baud rate equal to 50Ksamples/second?
In addition, how it is possible to modify the clock requirements for the slow run mode and so for the bus clock equal to 48MHz?
Thanks for your help
Best regards
Paola
