5.6 General Purpose I/O
The UE910 module is provided by a set of Configurable Digital Input / Output pins (CMOS 1.8V)
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 UE910 firmware and acts depending on the
function implemented.
The following table shows the available GPIO on the UE910:
