2.4.1. Configurations Pins
Telit M.2 module indicates the main serial interface applicable on the combination of 4
configuration pins. FN980 Family is configured as an USB 3.1 Gen 2.
Pin Signal State Interface Type
21 CONFIG_0 GND
USB 3.1 Gen 2
Port Configuration 0
(Applicable to WWAN only)
69 CONFIG_1 GND
75 CONFIG_2 GND
1 CONFIG_3 NC
Information – On the platform side, each of the CONFIG_0 to
CONFIG_4 signals needs to be fitted with a pull-up resistor. Based on
the state of the configuration pins on the Add-in Card, being tied to
GND or left No Connect (NC), the sensed pins will create a 4-bit logic
state that required decoding.

document.
