6.1 SQI Testing Procedure

When the DP83TC811 is active, the Signal Quality Indicator may be used to determine the quality of link based on SNR readings made by the device. Signal quality indication is accessible through bits[7:0] of SQI Register 0x0198 – Signal Quality Indication Register. SQI is continuously monitored by the DP83TC811 to allow for real-time link signal quality status.
