2.6. Control interface
This section describes the power-on/off, wake-up and reset interface on how to control the
module.
2.6.1. Power-on Signal
The POWER_ON is an active Low input signal used to enable or disable the module. Do not
toggle the PERST# pin during power-on. This signal has the highest priority over the wakeup,
the alarms signals, and the digital control pins.
There are three possible states of the module:
Module Off - VCC is not present.
Module Enabled - VCC is supplied, and the module is enabled.
Module Disabled - VCC is supplied, and the module is disabled.
The state transitions are defined as follows:
When voltage is applied to VCC, the module shall enter the Module Disabled
state.
