Low power configuration support, defining the CPU sleep state exit event

There are multiple HW events that may terminate a low-power hardware cycle. These are separated in two main families:

• Interrupt event (external interrupt)
• external event (not interrupt related)

Moreover, there is some time when the CPU must NOT enter sleep mode for a given amount of time. This can be set with this CPUSleep configuration state.

FIXME: the sleep trigger and the sleep constraints shoud be defined in separated types and calls.

Variants

WaitForInterrupt = 0

Enter sleep mode and wait for external interrupt

WaitForEvent = 1

Enter sleep mode and wait for external event

ForbidSleep = 2

Disable any enter to the low power mode

AllowSleep = 3

Re-enable low power

Trait Implementations

impl From<CPUSleep> for u32

fn from(mode: CPUSleep) -> u32

Converts to this type from the input type.

impl TryFrom<u32> for CPUSleep

type Error = Status

The type returned in the event of a conversion error.

fn try_from(mode: u32) -> Result<CPUSleep, Self::Error>

Performs the conversion.
