Figure 3.2. Energy Mode indicator
Note
There are five different Energy Modes (EM0-EM4) in the EFM32TG, see Table 3.1 (p. 8) . The
EFM32TG is designed to achieve a high degree of autonomous operation in low energy modes. The
intelligent combination of peripherals, RAM with data retention, DMA, low-power oscillators and short
wake-up times, makes it attractive to remain in low energy modes for long periods and thus saving
energy consumption.
Tip
Throughout this document, the first figure in every module description contains an Energy Mode
Indicator that shows in which energy mode(s) the module can operate (see Table 3.1 (p. 8) ).
