Suspend

Port Enabled Bit and Suspend bit of this register define the port states

When in suspend state, downstream propagation of data is blocked on this port, except for port reset. The blocking occurs at the end of the current transaction, if a transaction was in progress when this bit was written to 1. In the suspend state, the port is sensitive to resume detection. Not that the bit status does not change until the port is suspend and that there may be a delay in suspending a port if there is a transaction currently in progress on the USB.

A write of zero to this bit is ignored by the host controller. The host controller will unconditionally set this bit to a zero when:

1. Software sets the Force Port Resume bit to a zero(from a one).
2. Software sets the Port Reset bit to a one(from a zero).

If host software sets this bit to a one when the port is not enabled(i.e. Port enabled bit is a zero), the results are undefined.

This field is zero if Port Power is zero.

The default value in this field is ‘0’.

Value on reset: 0

Trait Implementations

impl Clone for SUSPEND_A

fn clone(&self) -> SUSPEND_A

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SUSPEND_A

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<SUSPEND_A> for bool

fn from(variant: SUSPEND_A) -> Self

Converts to this type from the input type.

impl PartialEq for SUSPEND_A

fn eq(&self, other: &SUSPEND_A) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
