8. POWER MODES
Power-off → Power-on 1, 4 Wake-up event:
• rising edge on Terminal 15
• rising edge on Wake-up input
• reception of wake-up pattern on a wake-up enabled CAN
interface
• reception of wake-up pattern on a wake-up enabled
100BASE-T1 interface
• Real-Time Clock with configured alarm-time and date
Power-on → Suspend At application request
Power-on → Power-off 2 At application request
Power-on → Disconnected 3 Terminal 30 disconnected from power supply
Suspend → Power-on Wake-up event:
• rising edge on Terminal 15
• rising edge on Wake-up input
• reception of wake-up pattern on a wake-up enabled CAN
interface
• reception of wake-up pattern on a wake-up enabled
100BASE-T1 interface
• Real-Time Clock with configured alarm-time and date
• touch event
Suspend → Disconnected 3 Terminal 30 disconnected from power supply
Suspend → Disconnected Terminal 30 disconnected from power supply
Note 1 Ensure that the device remains disconnected for a minimum of one second when switch-
ing the device off and on again (corresponds to power mode transition: Power-off →
Disconnect → Power-on).
Note 2 If the ”Aborted Startup” mechanism is activated, the last wake-up source was Terminal
15 or the Wake-up input and the state of the last wake-up source changes during the
boot process to LOW before the application is started, the device switches off automat-
ically (transition to Power-off mode). The “Aborted Startup” mechanism is activated by
default in the hardware abstraction layer configuration.
Note 3 Performing this mode transition is not recommended as all unsaved data will be lost, and
all operations running will be terminated in an uncontrolled manner. Users are advised
to power-off by setting Terminal 15 to low, and waiting until the application performs a
controlled shut down of the device.
Note 4 If a power-off is initiated by the application software while Terminal 15 and / or Wake-up
input are high, the device performs a power cycle and reboots.
