For OHCI Full-speed operations only, the user has to perform the following:
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 HS.
• Select UPLLCK as Input clock of OHCI part, USBS bit in PMC_USB register.
• Program the OHCI clocks (UHP48M and UHP12M) with USBDIV field in PMC_USB register.
• Enable OHCI clocks, UHP bit in PMC_SCER register.
• Enable UHP peripheral clock, bit (1 << AT91C_ID_UHPHS) in PMC_PCER register.
• Select PLLACK as Input clock of OHCI part, USBS bit in PMC_USB register.
• Program the OHCI clocks (UHP48M and UHP12M) with USBDIV field in PMC_USB register.
• Enable the OHCI clocks, UHP bit in PMC_SCER register.
USBDIV must be 9 (division by 10) if UPLLCK is selected.
USBDIV value is to calculated regarding the PLLACK value and USB Full-speed accuracy.
