Table 4-33 USB power control signals: pin assignments
USBx_PWRFAULT signals are high-active signals.
A logic high level signals the port is in an overcurrent situation.
The USB power control signals are optional signals and can be configured as
GPIOs. The following table lists the possible functions which are mutually exclusive
and may entail hardware modifications.
USB is the primary function used on the pins. Any other setup may require hardware
modifications which are not covered by standard module versions. For more
information on configuration and ordering please contact MicroSys.
