Figure 10-3 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.
This section describes the CPTS in the main domain. For CPTS in PCIe integration, please see PCIe Subsystem Precision Time Measurement (PTM) in Peripheral Component Interconnect Express (PCIe) Subsystem.
For CPTS in CPSW integration, please refer to CPSW0 Integration in Gigabit Ethernet Switch (CPSW).
