11.3. 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.
11.4. Using the Alarm Output GPIO6
The GPIO6 pad, when configured as Alarm Output, is controlled by the CL865 module and
will rise when the alarm starts and fall after the issue of a dedicated AT command.
This output can be used to controlling microcontroller or application at the alarm time.
