8.6.4.5.3 Either Internal or External 32-bit Timestamp Generation

Either the TSU internal timebase or the TSU external timebase can be selected for timestamping, by setting MCAN_TSU_TSCFG.TBCS to 0 or MCAN_TSU_TSCFG.TBCS to 1, respectively.

For each MCAN, MCAN_TSU_TSCFG.TSUE must be set to 1. See the following figure.
