Port timer register set is replicated for every port timer present (0 to 15) at the offsets listed for ports 1 to 15. Following are the port timer registers description:

|---|---|---|---|
| Port 0 Registers: 0x0200 to 0x023F | |||
| 0x0200 | TX0_CTIME_0 | RW | [31:0] - Snapshot of Port0 TX Timer’s CF Field [31:0] |
