The CPSW_5X error detection and correction logic uses the ECC Aggregator Module.
The ECC CPSW_ECC_VECTOR register is used to select which ECC RAM's status and control registers are currently being read or written as shown in Table 12-1744. The CPSW FIFO RAMs implement ECC only on packet headers. The packet data is protected by Ethernet CRC. The ALE and EST RAMs have complete ECC as normal.
| ECC RAM Number | CPSW RAM |
|---|---|
| 0 | ALE RAM |
| 1 | Port 0 FIFO RAM |
