DPs and DMs are not controlled by any PIO controllers. The embedded USB physical transceiv-
ers are controlled by the USB host controller.
The USB host controller requires a 48 MHz clock. This clock must be generated by a PLL with a
correct accuracy of ± 0.25%.
Thus the USB device peripheral receives two clocks from the Power Management Controller
(PMC): the master clock MCK used to drive the peripheral user interface (MCK domain) and the
UHPCLK 48 MHz clock used to interface with the bus USB signals (Recovered 12 MHz domain).
The USB host interface has an interrupt line connected to the Advanced Interrupt Controller
(AIC).
Handling USB host interrupts requires programming the AIC before configuring the UHP.
