3.3V Suspend/3.3V
PU 10K to 3.3V Suspend

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
PD 10K
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
PD 10K
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.

I/O CMOS
3.3V/3.3V
PU 10K to 3.3V
SDIO Card Detect. This signal indicates when a SDIO/MMC card is present.
SDIO_CLK
42
O CMOS
3.3V/3.3V
SDIO Clock. With each cycle of this signal a one-bit transfer on the command and each data line occurs. This signal has maximum frequency of 48 MHz.
SDIO_CMD
