NOTE:
To check if the device has been powered off or in PSM mode, the
hardware line PWRMON must be monitored. The device is powered
off when PWRMON goes low.
VBATT can be removed when PWRMON is in LOW state.
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
ML865G1 when the module is powered off or during an ON-OFF
transition.
WARNING:
Not following the recommended shut-down procedures might
damage the device and consequently void the warranty.
