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 ME910C1 firmware and acts
depending on the function implemented.

5.7.1. Using a GPIO as INPUT
The GPIO pads, when used as inputs, can be connected to a digital output of another
device and report its status, provided this device has interface levels compatible with the
1.8V CMOS levels of the GPIO.
If the digital output of the device to be connected with the GPIO input pad has interface
levels different from the 1.8V CMOS, then it can be buffered with an open collector
transistor with a 47K pull up to 1.8V supplied by VAUX/POWERMON R11 pad.
