I/O Description
In active mode, all functions of the module are available and all
processors are active. Radio transmission and reception can be
performed. Transitions to idle mode or PSM can be initiated in active
mode.
In idle mode, the module is in light sleep and network connection is
maintained; paging messages can be received; transitions to active
mode or PSM can be initiated in idle mode.
