Bits 7:5 – DRVTUNE[2:0] Driver Strength Tuning
Sets the lower 3 bits for the HS/FS/LS driver strength tuning.
Settings include the lower bits (PHY10.5:7) and the upper bit (PHY14.0:1).
| Value | Description |
|---|---|
| 11111 | Fastest rise fall time |
| 00000 | Slowest rise fall time |
Bits 4:0 – TUNE[4:0] Amplitude Tuning
Sets the upper 5 bits of the HS amplitude tuning.
Settings include the lower bits (PHY0C.5:7) and the upper bit the upper bit (PHY10.0:4) – setting of each bit location lowers the amplitude by the same amount regardless of location.
| Value | Description |
|---|---|
| 11111111 | Setting with the smallest amplitude |
| 10101100 | 4-‘0’ and 4-‘1’ is the middle amplitude |
| 00000000 | Setting with the largest amplitude |
