The USBHS provides a hardware device to interface a USB link to a data flow stored in a dual-port RAM (DPRAM).
In normal operation (SPDCONF = 0), the UTMI transceiver requires the UTMI PLL (480 MHz). In case of full-speed or low-speed only, for a lower consumption (SPDCONF = 1), the UTMI transceiver only requires 48 MHz.
