WAIT-ON state.
– Triggering event: VBAT > VBATMIN_LO
– Insertion of a charged main battery
– Precharge is active, main battery voltage rises
– Condition: VUPR > VPOR
Power-off transition: T2
– The system is in any state. Removal of all energy sources initiates a transition to NO SUPPLY state.
– Triggering event: VUPR < VPOR
– Main battery discharge or removal
– Backup battery discharge or removal
– Charger unplugged
– Condition: No more valid energy source
Switch-on transition: T3
– The system is in WAIT-ON state, able to accept a hardware switch-on condition, which initiates a
transition to ACTIVE state.
– Triggering event:
– Push button pressed and released (PWRON)
– Charging source plug (USB or external)
– RTC alarm
– Accessory plug (RPWRON)
– Insertion of a charged main battery or battery charge running (enabled by default)
– Software reset (following transition T4)
– USB ID plug insertion (disabled by default)
– Condition: VBAT > VBATMIN_HI and no thermal shutdown active
Switch-off transition: T4
– System is powered and in ACTIVE or SLEEP state. A hardware condition may initiate a transition to reach
WAIT-ON state.
– Triggering event:
– Group DEVOFF command (software) (if all other subsystems groups are OFF)
– Thermal shutdown
– Primary watchdog timer expired
– Software reset (followed by transition T3)
– Long key press (10 seconds) on PWRON
Sleep-on transition: T5
– System is powered and in ACTIVE state. A hardware condition initiates a transition to SLEEP state.
– Triggering event: Subsystem group sleep command (hardware) (PREQ# balls)
– Condition: All other subsystem groups are SLEEP or OFF.
Sleep-off transition: T6
– System is powered and in SLEEP state. A hardware condition initiates a transition to ACTIVE state.
– Triggering event:
– Subsystem group active command (hardware) (PREQ# balls)
– Warm reset (reinitialization of the TWL6030 device)
Active reset transition: T7
– System is powered and in ACTIVE state. A hardware condition initiates a reset, system remains in
ACTIVE state.
– Triggering event: Warm reset (reinitialization of the TWL6030 device)
Backup-on transition: T8
– System is powered and in ACTIVE, SLEEP, or WAIT-ON state. The detection of a low main battery
initiates the transition to BACKUP state.
– Triggering event: Battery voltage < VBATMIN_LO (discharge/removal)
