NOTE:
In order to avoid a back powering effect it is recommended to avoid having any HIGH logic
level signal applied to the digital pins of the module when it is powered OFF or during an
ON/OFF transition.
10.3.
Using a GPIO Pad 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.
10.4.
Using the Temperature Monitor Function
10.4.1.
Short Description
The Temperature Monitor is a function of the module that permits control of its internal
temperature and if properly set (see the #TEMPMON command on AT Interface guide) raises
to High Logic level a GPIO when the maximum temperature is reached.
