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 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 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.
Description
SDIO Card Detect. This signal indicates when a SDIO/MMC card is present.
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 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. Used to drive an external LED to indicate when transfers occur on the bus.
SDIO Write Protect. This signal denotes the state of the write-protect tab on SD cards.
SDIO Power Enable. This signal is used to enable the power being supplied to a SD/MMC card device.
SDIO Data lines. These signals operate in push-pull mode
