TTControl Vision 307 - Power On;Off Sequence; Maximum Ratings; Characteristics; External Wake-Up

6. SPECIFICATION OF INPUTS AND OUTPUTS
6.3.3 Power on/off sequence
The device boots if:
• Terminal 15 is powered (typically BAT+), or
• Wake-up input is powered (typically BAT+)
Once the device has started, the application software is responsible for saving all data to flash memory
before it powers down the device. This is necessary to ensure data integrity.
