The TDC state machine supports the following four user commands:
The TDC conversion starts when the start event edge occurs, which is useful for frequency measurements.
The TDC conversion starts immediately when the start event level occurs. Precise edge-to-edge measurement is not assured unless the user controls the event source. In the latter case, the user must ensure that the start event does not arrive until AUX_TDC:STAT.STATE is less than 0x5, which takes approximately 420 ns.
Forces the state machine to abort an ongoing TDC measurement. Do not write this command if AUX_TDC:STAT.STATE equals any of the following values:
Failure to comply may stall the TDC in these states.
Clears results and status registers.
For further description, see AUX_TDC:CTL in Section 20.8.5.
