USB high-speed regulator

Hi, 

 

3V is generated from VBUS using LDO_USB.
This 3V is for Full-Speed or Low-Speed.
These are described in 12.4.1.1.3 of the reference manual.

However, high speed works at 400mV.
Which regulator outputs 400mV?

Is it possible to change this 400mV output?
(Looking for the same function as the OUTPUT_TRG bit in the PMU_REG_3P0 register)

 

Many thanks,

Yoshida
