2.2.6 CPSW

The CPSW has its Ethernet events connected to its embedded CPTS, to support IEEE 1588 v2 protocols on the interface. The CPSW subsystem architecture is similar to previous devices and thus not explained in detail in this document. For more information, see the CPSW section of the device-specific TRM.
