The following table describes rx_change_fail_code output port encoding:
| Code | Description |
|---|---|
| 0 | Reserved |
| 1 | When a change of the RX SDI mode is requested that requires changing the RXCDR_CFG2 attribute in the GT transceiver, the UHD-SDI control module attempts to do a DRP write cycle to change that attribute. If the UHD-SDI DRP control module detected a mismatch between the written RXCDR_CFG2 value and its actual content after retries, the sequence fails with this failure code. |
| 2 | When a change of the RX SDI mode is requested that requires changing the RXOUT_DIV attribute in the GT transceiver, the UHD-SDI control module attempts to do a DRP write cycle to change that attribute. If the UHD-SDI DRP control module detected a mismatch between the written RXCDR_CFG2 value and its actual content after retries, the sequence fails with this failure code. |
| 3 | The gtwiz_reset_rx_datapath_in port of the GT Wizard IP is asserted after completing a series for DRP and GT port during a dynamic change to reset the GT RX portion. If the gtwiz_reset_rx_done_out port of GT Wizard IP failed to assert after retries, the sequence fails with this failure code. |
| 4 | When a change of the RX SDI mode is requested that requires changing the RXDATA_WIDTH attribute in the GT transceiver, the UHD-SDI control module attempts to do a DRP write cycle to change that attribute. If the UHD-SDI DRP control module detected a mismatch between the written RXDATA_WIDTH value and its actual content after retries, the sequence fails with this failure code. |
| 5 | When a change of the RX SDI mode is requested that requires changing the RXINT_DATAWIDTH attribute in the GT transceiver, the UHD-SDI control module attempts to do a DRP write cycle to change that attribute. If the UHD-SDI DRP control module detected a mismatch between the written RXINT_DATAWIDTH value and its actual content after retries, the sequence fails with this failure code. |
