◆ CONF_MCAN_ELEMENT_DATA_SIZE

#define CONF_MCAN_ELEMENT_DATA_SIZE 8

The value should be 8/12/16/20/24/32/48/64.

◆ CONF_MCAN_FBTP_FBRP_VALUE

#define CONF_MCAN_FBTP_FBRP_VALUE 5

Data bit Baud Rate Prescaler

◆ CONF_MCAN_FBTP_FSJW_VALUE

#define CONF_MCAN_FBTP_FSJW_VALUE 3

Data bit (Re)Synchronization Jump Width

◆ CONF_MCAN_FBTP_FTSEG1_VALUE

#define CONF_MCAN_FBTP_FTSEG1_VALUE 10

Data bit Time segment before sample point

◆ CONF_MCAN_FBTP_FTSEG2_VALUE

#define CONF_MCAN_FBTP_FTSEG2_VALUE 3

Data bit Time segment after sample point

◆ CONF_MCAN_NBTP_NBRP_VALUE

#define CONF_MCAN_NBTP_NBRP_VALUE 2

The setting of the nominal bit rate is based on the PCK5 which is 30M which you can change in the conf_clock.h. Below is the default configuration. The time quanta is 30MHz / (2+1) = 10MHz. And each bit is (1 + NTSEG1 + 1 + NTSEG2 + 1) = 20 time quanta which means the bit rate is 10MHz/20=500KHz. Nominal bit Baud Rate Prescaler
