Enum FlashSleep 

#[non_exhaustive]
pub enum FlashSleep {
    Never,
    FlashDoze,
    FlashDozeWithFlashWake,
}

Settings for gating power to on-chip flash

Applies to both “light” WFE sleep, as well as Deep Sleep. Requires that

FlashDoze

Disables flash memory accesses and places flash memory in Low-Power state whenever the core clock is gated (CKMODE > 0) because of execution of WFI, WFE, or SLEEPONEXIT. Other bus masters that attempt to access the flash memory stalls until the core is no longer sleeping.

FlashWake

Specifies that when this field becomes 1, an attempt to read the flash memory when it is in Low-Power state because of FLASHCR[FLASHDIS] or FLASHCR[FLASHDOZE], causes the flash memory to exit Low-Power state for the duration of the flash memory access.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Never

Don’t ever set the flash to sleep

FlashDoze

Set FlashDoze

This setting is only effective if CoreSleep has been configured with at least the WfeGated option or deeper.

FlashDozeWithFlashWake

Set FlashDoze + FlashWake

This setting is only effective if CoreSleep has been configured with at least the WfeGated option or deeper.
