Could you please check below questions?

Could you please suggest the register address for below SQI related register? I only find the worst case SQI value since last read is 0x871h. 

1. Current SQI is SNA
2. Current SQI value
3. Worst case SQI is SNA

Thanks!

Hi Ethan,

Can you please let me know what SNA means?

Hi Gokul,

Please see below the feedback from customer. 

SNA: it is a flag that means if the value is valid, please check if 720s Register have this bit?

Important Question is:

Normally we can get 8 levels of SQI,

which register stored the current SQI value that can tell me what SQI level at current time?

If the register address 0x871 bit 1-3 is the current SQI value, how can I get related SQI level from the register?   

Thanks!
