66.4.5.2 External 16-bit Timestamp Generation

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

Figure 66-3. 16-Bit Timestamping with External Timebase

Timestamping uses the value of CV in the Timer Counter Channel 0 register (TC_CV0) of TC_TO_MCAN. TC_TO_MCAN may use the generic clock (GCLK) from the Power Management Controller. Refer to the section "Timer Counter (TC)" for more details about clock source selection.
