20.4.5.3.3.2 Synchronous Counter Start – Ignore 0 Stop Events
In this scenario the user:
- Wants to measure the time between the start event that follows falling edge and the first stop event
- Sets AUX_TDC:TRIGCNTCFG.EN = 0 to disable the stop counter
- Starts the TDC measurement by writing AUX_TDC:CTL.CMD = 1
- Assures that the stop event goes high later than the start event
Figure 20-19 shows the scenario for synchronous counter start – ignore 0 stop events.

Table 20-27 lists the associated timing requirements for this scenario.
