title: STMicroelectronics STM32 USB HS PHY controller binding
|
|
|
|
description:
|
|
|
|
The STM32 USBPHYC block contains a dual port High Speed UTMI+ PHY and a UTMI
|
|
switch. It controls PHY configuration and status, and the UTMI+ switch that
|
|
selects either OTG or HOST controller for the second PHY port. It also sets
|
|
PLL configuration.
