UIM_CLK: Clock line, output from M.2 WWAN card to the UIM module.
UIM_RST#: Reset signal line, sent from M.2 WWAN card to the UIM module.
Please be aware that all signals related to User Identity Modules are managed directly by the M.2 card circuitry, they don't involve neither carrier board's nor COM
Express module's management.

COM Express module's WAKE1# signal.
WWAN_RST#: WLAN specific reset Signal, derived from the CB_RESET signal sent from COM
Express module to all PCI-e devices available on the board.
CLK_REQ2#: PCI Express Clock Request Input. This signal shall be driven low by the module
inserted in the M.2 WWAN slot, in order to ensure that the PCI-e clock buffer available on the
carrier board makes available the reference clock for this slot (i.e. PCIE_CLK2+/PCIE_CLK2-).
PWR_OFF#: 1kOhm pullup to 3.3V_A
W_DISABLE1#_B: this signal can be used to enable/disable the M.2 WWAN module plugged
in slot CN12. This signal is directly managed using jumper JP1, as described in the table below.
W_DISABLE2#_B: this signal can be used to enable/disable the M.2 WWAN module plugged
in slot CN12. This signal is directly managed using jumper JP2, as described in the table below.
M.2_WAKE#: Board's Wake Input, it must be externally driven by the M.2 WWAN module
inserted in the slot when it requires waking up the system. This signal is connected to COM
Express module's WAKE0# signal.
On the WWAN slot are also available the signals for interfacing to microSIM cards (which can
be hosted in the microSIM slot CN14), so that it is possible to use M.2 WWAN modems.
UIM_PWR: Power line for UIM module.
UIM_DATA: Bidirectional Data line between M.2 WWAN card and UIM module.
