The majority of the DCMAC Subsystem attributes are accessible using the AXI4-Lite interface.
Single-bit attributes are generally of type boolean string and thus should be set to "TRUE" or "FALSE" when overriding the Unisim default. The following single-bit attributes are of type binary and thus should be set to 1 or 0 when overriding the Unisim default:
- C2_CTL_RX_DATA_RATE
- C2_CTL_TX_DATA_RATE
- C4_CTL_RX_DATA_RATE
- C4_CTL_TX_DATA_RATE
- CTL_RX_ECC_ERR_CLEAR
- CTL_TX_ECC_ERR_CLEAR
- CTL_TX_ECC_ERR_COUNT_TICK
