VDD_IN
Main power source from Carrier to Module
3.3V
3.3V power domain: Active while CARRIER_PWRON is high and CARRIER_SBY# is NOT active (i.e. both signals are high)
1.8V
1.8V power domain: Active while CARRIER_PWRON is high and CARRIER_SBY# is NOT active (i.e. both signals are high)
3.3Vsb
3.3V standby power domain: Active while CARRIER_PWRON is high (regardless of CARRIER_SBY#)
1.8Vsb
1.8V standby power domain: Active while CARRIER_PWRON is high (regardless of CARRIER_SBY#)
Sleep
Module is in its lowest power state
Runtime
Module is full on. CARRIER_PWRON is high and CARRIER_SBY# is NOT active (i.e. both signals are high)
Standby
Module is in standby state or higher
