5. DIGITAL SECTION

ME310G1 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 ME310G1 is ready to accept AT

commands. ME310G1 can be idle or connected.

• Sleep mode state: main baseband processor is intermittently switched ON and AT

commands can be processed with some latency. ME310G1 is idle with low current

consumption.

• Deep sleep mode state: PSM defined in 3GPP Release 12. Baseband is switched

OFF most of the time.
