The majority of the DCMAC Subsystem attributes are accessible using the AXI4-Lite interface.
CTL_RSVD4 attribute is used to enable or disable the timing arcs for Dynamic or Static configuration for the DCMAC Subsystem IP.
The values for CTL_RSVD4 are:
- CTL_RSVD4[31:0] = 32'h0 : DYNAMIC CONFIGURATION
- CTL_RSVD4[31:0] = 32'h1 : STATIC CONFIGURATION
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
