No direct transitions between EM1, EM2 or EM3 are available, as can also be seen from Figure 10.2 (p.
107) . Instead, a wakeup will transition back to EM0, in which software can enter any other low energy
mode. An overview of the supported energy modes and the functionality available in each mode is shown
in Table 10.1 (p. 108) . Most peripheral functionality indicated as "On" in a particular energy mode can
also be turned off from software in order to save further energy.
