WARNING:
POWERMON can be used to monitor only the power on but it cannot be used to monitor the
power off because it remains high. Instead AT#SYSHALT works in the same way as previous
GL865-DUAL/QUAD.
NOTE:
In order to prevent a back powering effect it is recommended to avoid having any HIGH logic
level signal applied to the digital pins of the GL865-DUAL/QUAD V3 when the module is
powered off or during an ON/OFF transition.
