The AUX TDC (AUX_TDC) peripheral is a high-precision TDC used to measure the time between a configurable start event and another configurable stop event. The TDC counts at either 96 MHz or 48 MHz, using both edges of a selected counter clock source.
TDC peripheral features are:
The TDC is typically used for the following:
The Sensor Controller and the System CPU share the TDC peripheral. TI's Power Manager uses the TDC peripheral for RCOSC calibration. Both masters must implement and honor resource sharing to use this peripheral. For details, see Section 20.4.3.3.
Figure 20-15 shows the block diagram of the TDC. It also shows the connections to the Oscillator Control (OSCCTL) module, which requires configuration to use the TDC.
