GPIO number Pin number Secondary function<br />
GPIO 1 64 Pulse Width Tone<br />
GPIO 2 62 USB Boot<br />
GPIO 3 60 Light Output PWM<br />
GPIO 4 58 Transmit active / LED Pulse Generator<br />
GPIO 5 68 SPI Chip Select 0<br />
GPIO 6 70 SPI Strobe Enable<br />

GPIO 8 72 SPI Data/Control Select<br />
Each general-purpose signal may be selected as inputs or outputs. GPIO1-GPIO8 may be used<br />
independently as a user-specified function, or may be used to provide modem control and status signals.<br />
Several examples of modem control signals are: power shutdown command, register/deregister on<br />
network command, and transmitter disable. Several examples of modem status signals are: registration<br />
status and ready-for-power-down status to be used with power shutdown command signal.<br />
