PCIE_TX6+/PCIE_TX6-: PCI Express lane #6, Transmitting Output Differential pair.
PCIE_RX6+/PCIE_RX6-: PCI Express lane #6, Receiving Input Differential pair.
mPCIE_CLK1+ / mPCIE_CLK1-: PCI Express Reference Clock for lane #6, Differential Pair.
USB5+ / USB5-: USB Port #5 differential pair.
PCIE_WAKE#: Board's Wake Input, it must be externally driven by the miniPCI-e module
inserted in the slot when it requires waking up the system.
PCIE_RST#: Reset Signal that is sent from COM Express
available on the board.
mPCIE_CLOCK_REQUEST_1#: PCI Express Clock Request Input. This signal shall be driven
low by any module inserted in the miniPCI express slot, in order to ensure that the PCI-e clock
buffer available on the carrier board makes available the reference clock for the miniPCI-e slot.
SMB_CK: SM Bus control clock line for System Management, managed by the COM
Express module.
SMB_DAT: SM Bus control data line for System Management, managed by the COM
Express module.
On the slot #1 are also available the signals for interfacing to miniSIM cards, so that it is
possible to use miniPCI Express modems.
UIM_PWR: Power line for UIM module.
UIM_DATA: Bidirectional Data line between miniPCI-express card and UIM module.
UIM_CLK: Clock line, output from miniPCI-express card to the UIM module.
UIM_RESET: Reset signal line, sent from miniPCI-express card to the UIM module.
UIM_VPP: UIM Proprietary Use signal.
Please be aware that all signals related to User Identity Modules are managed directly by the
miniPCI-express card circuitry, they don't involve neither carrier board's nor COM Express
module's management. The CCOMe-965 carrier board embeds only clamping diodes for
ESD protection on UIM signal and voltage lines.
Similarly to miniPCI-express slot #0 other three SMT RED LEDs are present near this Mini PCI-
Express Card Slot to show the presence of an eventual Wi-Fi PCI-Express Card inserted.
Green Led, D6: Wireless_WAN #1 present
Yellow Led, D5: Wireless_LAN #1 present
Red Led, D4: Wireless_PAN #1 present
