Stratix 10 E-tile Transceiver Native PHY : questions with "altera_xcvr_rcfg_10_reconfig_parameters.m

[s10user]

Hi,

 Some questions about the  "altera_xcvr_rcfg_10_reconfig_parameters.mif" file:

1.What if the bits of the registers that are not written to are not used?

   for example : 

      00F : 00013C000; -- [34:16]-DPRIO address=0x013; [15:8]-bit mask=0xC0; [7:7]-         

       hssi_xcvr_rxfifo_wr_full=prevent_wr_rx_fifo_full(1'h0); [6:6]-   

       hssi_xcvr_rxfifo_rd_empty=prevent_rd_rx_fifo_empty(1'h0);

        if data[5:0] are unsed,Writing these bits has no effect?

2.Can you give the description of an unlisted address, such as 0xe8?

Thank you

Hi,

1) With reference to the example provided in the user guide, it seems to have no effect. Please refer to the link below for mor info.

https://www.intel.com/content/www/us/en/docs/programmable/683723/current/reconfiguration-files.html

2) Please only use the registers which are defined in the user guide, those registers might be used for some internal configuration.

Thank you
