Bit 7 – SQIERR SQI ERR

This bit will be set when an error has occurred during the SQI statistic accumulation period.

ValueDescription
0 No error detected during SQI measurement
1 Error has been detected during SQI measurement

Bit 6 – SQIVLD SQI Valid

This bit is set when the SQI measurement is valid and may be read from SQIVAL.
ValueDescription
0 SQI estimation is not complete or valid
1 SQI estimation is complete and valid
