Hi nasser

The datasheet SNLS456A have the details of reg 0x30,the description of bit 4 says that "Force reload of seed into PRBS checker LFSR without holding the checker in reset."what does that mean?

thank you

Hi Zhao,
You should have access to the SNLU182C - DS280DF810 programming guide. This is part of the DS280DF810 design documents. Please register at TI.COM, use your company email address, and send me email at nasser.mohammadi@ti.com so we can provide you with access to this and other design documents.

Additionally, we have listed register settings for enabling PRBS generator and checker as well.
