Dear TI Engineer.

I want to know about the resistor ES_BIT_SEL[2:0] in 0x58[6:4].

What does Eyescan bit Select means?

Is there anyone who can tell me?

Thank you.

Best Regards,

Hello Chang,

For the eyescan diagnostics, data is accumulated into 8-bit words for analysis. However, only data from the bit position specified via ES_BIT_SELECT[2:0] is analyzed. In other words, only eyescan errors associated with data output at this bit position will accumulate in the bert_counter.
