PCIE_CTL0_WAKE: Board
’
s Wake Input, 3.3V_RUN active low signal with 47k
Ω
pull-up
resistor. It must be externally driven by the Connectivity module plugged in the slot when it
requires waking up the system.
Here following the signals related to the USB interface:
/ USB_P1-: USB Port #1 differential pair; it is managed by Microchip USB4604 Hub
controller
’
s Downstream Port #1.
M2_KEYB_PWROFF#: Power Off signal for plugged modules, usually used in battery-powered
systems. Fixed 2k2
Ω
pull-up @ 1.8V_RUN.
M2_KEYB_W_DIS1# / M2_KEYB_W_DIS2#: M.2 module functionality disable signals #1 and
#2, active low outputs.
UIM_RESET: Reset signal line, sent from M.2 WWAN card to the UIM module.
UIM_DATA: Bidirectional Data line between M.2 WWAN card and UIM module.
UIM_CLK: Clock line, output from M.2 WWAN card to the UIM module.
UIM_PWR: Power line for UIM module.
SIM_DETECT: Sim Detect signal coming from module. It can be forced to be low through the
insertion of jumper JP1.
CONF0, CONF1, CONF2, CONF3: Configuration inputs, +3.3V_RUN signals with 10k
Ω
pull-
up. These signals are necessary to switch between the S-ATA and the PCI-e signals on the pins 29/31/35/37/41/43/47/49 of connector CN37. The selection is
automatic, according to M.2 specifications for Socket2 Add-In Card configuration Table.
