Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7-5 | EDGE_RATE[2:0] | RW | 4h | Set the Class-D output edge rate control to
0 = Reserved 1 = Reserved 2 = 29ns 3 = 25ns 4 = 14ns 5 = 13ns 6 = 12ns 7 = 11ns |
4-3 | ISNS_SCALE[1:0] | RW | 0h | Sets the full-scale value of Isense channel. Should be changed based on the speaker DC impedance R0.
0 = 8ohm, Isense full-scale = 1.25A 1 = 6ohm, Isense full-scale = 1.5A 2 = 4ohm, Isense full-scale = 1.75A 3 = Reserved |
2 | Reserved | RW | 0h | Reserved |
1-0 | BOOST_ILIM[1:0] | RW | 3h | Sets the boost current limit to
0 = 1.5A 1 = 2A 2 = 2.5A 3 = 3A |
