Pin Description
USB VBus On/Off: Bus Power Control Port
In order to use this module, other parts of the system must be configured correctly, as described
below.
The UOTGVBOF and UOTGID 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.
Table 39-3.
The clock for the UOTGHS bus interface is generated by the Power Management Controller.
This clock can be enabled or disabled in the Power Management Controller. It is recommended
to disable the UOTGHS before disabling the clock, to avoid freezing the UOTGHS in an unde-
fined state.
The UOTGHS can work in two different modes:
• If UOTGID is used, the I/O Controller must be configured to enable the internal pull-up
• If UOTGVBOF or UOTGID is not used by the application, the corresponding pin can be used
• Normal mode (SPDCONF =1) where High speed, Full speed and Low speed are available.
• Low-power mode (SPDCONF =0) where Full speed and Low speed are available.
