Digital interface
The MC7710 Mini Card provides the general purpose digital I/O (GPIO) signals
listed in
Table 4-7:
• By default, all GPIO pins are set as inputs.
• Voltage should not be applied until > 1s after VCC is applied to the minicard.
• GPIO pins are available for OEM-defined purposes but may, in future
firmware releases, be allocated by Sierra Wireless for specific functionality.
• For applications not requiring GPIO functionality, leave these pins not
connected on the host.
