7.5 Power modes shutdown sequencing
When entering stop or other low-power modes, the clocks are shut off in an orderly
sequence to safely place the chip in the targeted low-power state. All low-power entry
sequences are initiated by the core executing an WFI instruction. The ARM core's
outputs, SLEEPDEEP and SLEEPING, trigger entry to the various low-power modes:
When entering the non-wait modes, the chip performs the following sequence:
In wait modes, most of the system clocks are not affected by the low power mode entry.
The Core Clock to the ARM Cortex-M4 core is shut off. Some modules support stop-in-
wait functionality and have their clocks disabled under these configurations.
The debugger modules support a transition from stop, wait, VLPS, and VLPW back to a
halted state when the debugger is enabled. This transition is initiated by setting the Debug
Request bit in MDM-AP control register. As part of this transition, system clocking is re-
established and is equivalent to normal run/VLPR mode clocking configuration.
7.6 Module Operation in Low Power Modes

of the low power modes. (Debug modules are discussed separately; see
