USB over-current sense, USB channels 0 and 1. A pull-up for this line shall be present on the Module. An open drain driver from a USB current monitor on the Carrier Board may drive this line
low.
Do not pull this line high on the Carrier Board.

USB_ID
92
I CMOS
3.3V Suspend/3.3V
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
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.

SDIO_CD#
43
I/O CMOS
3.3V/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
45
I/O OD/PP CMOS
3.3V/3.3V
SDIO Command/Response. This signal is used for card initialization and for command transfers. During initialization mode this signal is open drain. During command transfer this signal is in push-
pull mode.
SDIO_LED
44
O CMOS
3.3V/3.3V
SDIO LED. Used to drive an external LED to indicate when transfers occur on the bus.
SDIO_WP
46
I/O CMOS
3.3V/3.3V
SDIO Write Protect. This signal denotes the state of the write-protect tab on SD cards.
SDIO_PWR#
