SD-SDI 8bit

Hello, SD-SDI megacore supports SD-SDI 10bit mode, however I need 8 bit support. Is it possible to use 8bit mode or it will be impossible to sync the signal? If two LSB bits will be left unconnect...

Hi again,

Please feed tx_data(9..2) with the 8bit data.

I think that feeding the tx_data(1..0) with always "00" is OK but also look like what you did is OK.

The simulation is working for me with the Modelsim Altera Edition.

I used the SDI 10.1 User guide and Quarts 10.1.

I think the simulation will be a good way to check that every thing you did is OK or not.

BR,
