1.2.5.3 Supply Controller Configuration

Figure 1-43. Supply Monitor Configuration

The Demo Meter application enters a Low-Power mode (back-up mode) in two ways:

  • When the user types the command DCB in the console
  • When the Scroll-up button is pressed and, then, without releasing it, Scroll-down button is pressed
Figure 1-44. Backup Mode Configuration

The system wakes up when the user pushes the TAMPER or FWUP buttons if the main power supply was restored.

Note: The user can easily change the code to add other transition modes to Low-Power mode. In some cases, it could be useful to switch to Low-Power mode when a power outage is detected or depending on the microcontroller voltage supply monitor information. These transitions could be combined with writing on external memory to store relevant data.
