In order to use this module, other parts of the system must be configured correctly, as described
below.
The USB_VBOF and USB_ID pins are multiplexed with I/O Controller lines and may also be
multiplexed with lines of other peripherals. In order to use them with the USB, the user must first
configure the I/O Controller to assign them to their USB peripheral functions.
If USB_ID is used, the I/O Controller must be configured to enable the internal pull-up resistor of
its pin.
If USB_VBOF or USB_ID is not used by the application, the corresponding pin can be used for
other purposes by the I/O Controller or by other peripherals.
The clock for the USBB bus interface (CLK_USBB) is generated by the Power Manager. This
clock is enabled at reset, and can be disabled in the Power Manager. It is recommended to dis-
able the USBB before disabling the clock, to avoid freezing the USBB in an undefined state.
The 48 MHz USB clock is generated by a dedicated generic clock from the Power Manager.
Before using the USB, the user must ensure that the USB generic clock (GCLK_USBB) is
enabled at 48MHz in the Power Manager.
The USBB interrupt request line is connected to the interrupt controller. Using the USBB inter-
rupt requires the interrupt controller to be programmed first.
