Description

The SAM7 has (software-controlled) internal pull-up resistors, but no pull-down resistors.

Thus, we cannot simply attach the sim card detect contact between 3V3 and the GPIO. We either add a pull-down (bad, as it adds a component and power consumption), or we connect the SW2 pin of the SIM card socket to GND instead of 3V3
