Unconditional shutdown

Wake from deep sleep mode

ME310G1 supports Power Saving Mode (PSM) functionality defined in 3GPP Release 12.

When Periodic Update Timer expires, ME310G1 shuts down until the next scheduled wake-

up time.

Asynchronous event controlled by host can wake up from deep sleep mode by asserting

ON_OFF*/WAKE* pin LOW for at least 5 seconds.

Host can detect deep sleep mode by polling PWRMON pin if PSM has been previously

configured.

“Unconditional shutdown”
