CLK_REQ0#: PCI-e Clock request. Bidirectional signal, electrical level +3.3V_ALW with a 10K
Ω
pull-up resistor
SUS_CLK: 32.768kHz Clock provided by the ADLER board to the module plugged in the slot CN15. +3.3V_ALW electrical level.
PLT_RST#: Reset Signal that is sent from the SoC to all PCI-e devices available on the board (i.e. the GbE controllers and the modules plugged in the CN14 slot). It
is a 3.3V active-low signal with 100k
Ω
pull-down.
KEYE_W_DISABLE1#: M.2 Key E module disable signal #1, 3.3V_ALW active low output
KEYE_W_DISABLE2#: M.2 Key E module disable signal #2, 3.3V_ALW active low output

m miniSIM Combo Slot
On ADLER board there is also a socket, for the use of standard SD cards,
to be used as Mass Storage Device and/or Boot Device.
Moreover, ADLER board can accept also miniSIM cards, for use of M.2
Key B modems.
Both these cards can be inserted in the dedicated slot of connector
CN13, which is a combo
μ
SD/MMC + miniSIM connector, push-push
type, 2.7 mm global height, type AVX p/n 009162006501150 or
equivalent. Pinout here reported is related only to signal routing on specific connector; internally
the pin-out is the same of any standard SD/MMC 4.0 and miniSIM card.
For ESD protection, on all signal lines are placed clamping diodes for voltage transient
suppression.
Signals related to UIM (SIM) card are described in paragraph 3.3.7 for description
.
Signals
related to SD cards are the following:
SDIO_CD#: Card Detect Input.
SDIO_CLK: SD Clock Line (output).
SDIO_CMD: Command/Response bidirectional line.
SD_DATA[0÷3]: SD Card data bus. SD_DATA0 signal is used for all communication modes. SD_DATA[1÷3] signals are required for 4-bit communication mode.
SDIO_VDD: +3.3V_ALW SD dedicated Power rail
