In order to use this module, other parts of the system must be configured correctly, as described
below.
The USBC pins may be multiplexed with the I/O Controller lines. The user must first configure
the I/O Controller to assign the desired USBC pins to their peripheral functions.
The USB VBUS line should be connected to a GPIO pin and the user should monitor this with
software.
If the CPU enters a sleep mode that disables clocks used by the USBC, the USBC will stop func-
tioning and resume operation after the system wakes up from sleep mode.
The USBC has two bus clocks connected: One High Speed Bus clock (CLK_USBC_HSB) and
one Peripheral Bus clock (CLK_USBC_PB). These clocks are generated by the Power Man-
ager. Both clocks are enabled at reset, and can be disabled by the Power Manager. It is
recommended to disable the USBC before disabling the clocks, to avoid freezing the USBC in
an undefined state.
The 48MHz USB clock is generated by a dedicated generic clock from the SCIF module. Before
using the USB, the user must ensure that the USB generic clock (GCLK_USBC) is enabled at
48MHz in the SCIF module.
The USBC interrupt request line is connected to the interrupt controller. Using the USBC inter-
rupt requires the interrupt controller to be programmed first.
The USBC asynchronous interrupt can wake the CPU from any sleep mode:
• The Wakeup Interrupt (WAKEUP)
