Dynamic Reconfiguration Ports
The GTH transceiver dynamic reconfiguration ports (DRP) can be accessed via the training
ports of the 10-Gigabit Ethernet PCS/PMA IP core. The training ports are brought out to
VIOs - training_*_ch0 and training_*_ch1.
1. For reads:
°
Set the training_addr_ch* to a DRP address, example
h'00_007F
(TX_MARGIN_FULL_1, TX_MARGIN_FULL_0)
°
Set the training_rnw_ch* to
1
°
Toggle (
0 > 1 > 0
) enable_ch*
°
The read value will be available on training_rd_data_reg_ch*
2. For writes:
°
Set the training_addr_ch* to a DRP address example
h'00_007F
(TX_MARGIN_FULL_1, TX_MARGIN_FULL_0)
°
Set the training_wr_data for the above address as
h'AE9C
°
Set the training_rnw_ch* to
0
°
Toggle (
0 > 1 > 0
) enable_ch*
°
Read the value back following the instructions for Reads to verify that the write was
successful
