Figure 11-3 shows the architecture of the CPTS module.
The CPTS module is used to facilitate host control of time sync operations. The CPTS collects time sync events and then presents them to the host for processing. The types of time sync events are as follows:
The reference clock used for the time stamp (RCLK) can be derived from several sources.
