Battery Charging 1.2 port detection.

Default value: 0

Legal values: +11.36%, 0, -11.33%, -22.74%

txhsxvtune

string

Transmitter High-Speed Crossover Adjustment.
Adjusts the voltage at which the DP0 and DM0 signals cross while
transmitting in HS mode.

Default value: 0

Legal values: -13 mV, +13 mV, 0

txfslstune

string

FS/LS Source Impedance Adjustment.
Adjusts the low- and full-speed single-ended source impedance while
driving high.

txrisetune

string

HS Transmitter Rise/Fall Time Adjustment.
Adjusts the rise/fall times of the high-speed waveform.

Default value: 0

Legal values: +10%, 0, -12%, -25%

txrestune

string

USB Source Impedance Adjustment.
Adjusts the driver source impedance to compensate for added series
resistance on the USB.

Default value: 0

Legal values: +6.5 ohm, +3 ohm, 0, -2 ohm

txpreempamptune

string

HS Transmitter Pre-Emphasis Current Control.
Controls the amount of current sourced to DP0 and DM0 after a J-to-K or
K-to-J transition. The HS Transmitter pre-emphasis current is defined in
terms of unit amounts. One unit amount is approximately 4 mA and is
defined as 1x pre-emphasis current.

Default value: disabled

Legal values: disabled, 2x, 1x, 3x

txpreemppulsetune

string

HS Transmitter Pre-Emphasis Duration Control.
Controls the duration for which the HS pre-emphasis current is sourced
onto DP0 or DM0. The HS Transmitter pre-emphasis duration is defined in
terms of unit amounts. One unit of pre-emphasis duration is approximately
580 ps and is defined as 1x pre-emphasis duration.

Default value: 2x

Legal values: 2x, 1x
