5. DIGITAL SECTION
ME910G1 has four main operation states:
• OFF state: Vbatt is applied and only RTC is running. Baseband is switched OFF and
the only change possible is the ON state.
•
ON state: baseband is fully switched on and ME910G1 is ready to accept AT
commands. ME910G1 can be idle or connected.
• Sleep mode state: main baseband processor is intermittently switched ON and AT
commands can be processed with some latency. ME910G1 is idle with low current
consumption.
•
Deep sleep mode state: PSM defined in 3GPP Release 12. Baseband is switched
OFF most of the time.
