6.1 SQI Value Interpretation

Register bits 0x871[3:1] contain the SQI value. This register can be polled to understand the appropriate range of MSE values for each SQI value.

Table 6-1 SQI Values for Register Bits 0x871[3:1]
0x871 [3:1] OPEN ALLIANCE SQI MSE VALUES
0x0 SQI = 0 (Worst) MSE > 133
0x1 SQI = 1 11 < MSE ≤ 133
0x2 SQI = 2 7 < MSE ≤ 11
0x3 SQI = 3 5 < MSE ≤ 7
0x4 SQI = 4 4 < MSE ≤ 5
0x5 SQI = 5 3 < MSE ≤4
0x6 SQI = 6 2 < MSE ≤ 3
0x7 SQI = 7 (Best) MSE ≤ 2
