I CMOS
3.3V Suspend/3.3V
PU 10K to 3.3V Suspend
Connect to Overcurrent of USB Power Switch
Over current detect input 4. This pin is used to monitor the USB power over current of the USB Ports 6 and 7.
USB_ID
92
I CMOS
3.3V Suspend/3.3V
NC
USB ID pin.Configures the mode of the USB Port 1. If the signal is detected as being 'high active' the BIOS will automatically configure USB Port 1 as USB Client and
enable USB Client support. This signal should be driven as OC signal by external circuitry.
USB_CC
91
I CMOS
3.3V Suspend/3.3V
NC
USB Client Connect pin.If USB Port 1 is configured for client mode then an externally connected USB host should set this signal to high-active in order to properly make
the connection with the module's internal USB client controller.
If the external USB host is disconnected, this signal should be set to low-active in order to inform the USB client controller that the external host has been
disconnected.
A level shifter/protection circuitry should be implemented on the carrier board for this signal.
