DIGITAL SECTION
NE310L2 has four main operation states:
 OFF state: Vbatt is applied and only RTC is running. The Baseband is switched OFF
and the only possible change is the ON state.
 ON state: the baseband is fully switched on and NE310L2 is ready to accept AT
commands. NE310L2 can be idle or connected.
 Sleep mode state: the main baseband processor is intermittently switched ON and
AT commands can be processed with some latency. NE310L2 is idle with low
current consumption.
 Deep sleep mode state: PSM defined in 3GPP Release 12. Baseband is switched
OFF most of the time.
