Telit Wireless Solutions CE910-DC, Hardware User'S Manual, Page: 49 / 67

The CE910 module is provided by a set of Digital Input / Output pins
Input pads can only be read; they report the digital value (high or low) present on the pad at the read
time.
Output pads can only be written or queried and set the value of the pad output.
An alternate function pad is internally controlled by the CE910 firmware and acts depending on the
function implemented.
The following GPIOs are available on the CE910:
