5.7.2. Using a GPIO as OUTPUT
The GPIO pads, when used as outputs, can drive 1.8V CMOS digital devices or compatible
hardware. When set as outputs, the pads have a push-pull output and therefore the pull-up
resistor may be omitted.
External SIM Holder
Please refer to the related User Guide (SIM Holder Design Guides, 80000NT10001a).
NOTE:
There is no dedicated signal (SIMIN) for “Presence SIM” in the
ME310G1 pinout.
This feature can performed by connection of IO1 (Pad V11) or IO2
(Pad V13) or IO3 (Pad D7) or IO4 (Pad D9) or IO5 (Pad D11) or IO6
(Pad D13) to the switch embedded in the sim-holder.
SIM detection can be configured by specific AT Command.
Refer to SW User Guide or AT Commands Reference Guide for the
full description of this function.
WARNING:
Pull-up 470K is required across CTANK (ball N4) and switch
embedded in the sim-holder.
