60.4.5.2 External 16-bit Timestamp Generation

An external timebase is provided by TSU when MCAN_TSCC.TSS is set to 2. See the following figure.

Figure 60-3. 16-Bit Timestamping with External Timebase

Timestamping uses the value of the TSU counter. In this case, both the register in MCAN (external timebase) and the register in TSU must be programmed to configure the counter. See the following figure.
