Section 7.3 refers to the system CPU mode, so it is important to understand what this means.
The system CPU has three different operation modes: run, sleep, and deep sleep (see Table 7-3). Each mode is used to gate internal clocks in the system CPU, in addition to peripheral clocks that may be gated in accordance to the current system CPU mode. Deep sleep mode is, in some cases, one of several requirements for powering down voltage and power domains.
System CPU Mode | Description |
---|---|
Run mode | Wait For Interrupt (WFI) and Wait For Event (WFE) both inactive, CPU_SCB:SCR.SLEEPDEEP is don’t care |
Sleep mode | WFI or WFE active and CPU_SCB:SCR.SLEEPDEEP = 0 |
Deep sleep mode | WFI or WFE active and CPU_SCB:SCR.SLEEPDEEP = 1 |
