Operating Modes
This module has three operating modes, which can determine availability of functions for
different levels of power-saving.
Mode
Function
Active
In active mode, all functions of the module are available and all processors are
active. Data transmission and reception can be performed. Transitions to idle
or PSM mode can be initiated in active mode.
Idle
In idle mode, the module is in light sleep and network connection is maintained
(module in DRX/eDRX mode); paging messages can be received; transitions
to active mode or PSM can be initiated in idle mode.
PSM
In PSM, the module is in deeper sleep and only the 32kHz RTC is working.
The network is disconnected, and paging messages cannot be received either.
When MO (Mobile Originated) data are sent or the periodic TAU (Tracking
Area Update) timer T3412 expires, or when WAKE* drop edge trigger, the
module will be woken up.
