Figure 19-1 shows the various components that implement the high-resolution capture functionality of the eCAP module. Note that existing eCAP resources are reused, which requires that the eCAP module is set up before using the HRCAP enhancements. For simplicity, absolute timestamp measurements are recommended. See Section 19.3 for more details.
All HRCAP measurements are relative-time measures, in terms of minimum step size. Calibration hardware as well as software functions, have been provided to convert relative-time measurements to time-converted measurements in terms of seconds. The calibration hardware and software is only required if time-converted measurements are required.
