3.1.6 Power modes
The i.MX 8M Dual / 8M QuadLite / 8M Quad processor support the following power modes:
• RUN Mode: All external power rails are on, CPU is active and running; other internal modules can
be on/off based on application.
• IDLE Mode: When there is no thread running and all high-speed devices are not active, the CPU
can automatically enter this mode. The CPU can be in the power-gated state but with L2 data
retained, DRAM and the bus clock are reduced. Most of the internal logic is clock gated but still
remains powered. The M4 core can remain running. Compared with RUN mode, all the external
power rails from the PMIC remain the same, and most of the modules still remain in their state.
• SUSPEND Mode: The most efficient power saving mode where all the clocks are off and all the
unnecessary power supplies are off.
• SNVS Mode: This mode is also called RTC mode. Only the power for the SNVS domain remains
on to keep RTC and SNVS logic alive.
• OFF Mode: All power rails are off.
