Line Status

These bits relect the current logical levels of the D+ (bit11) and D- (bit10) signal lines. These bits are used for detection of low-speed USB devices prior to port reset and enable sequence. This read only field is valid only when the port enable bit is zero and the current connect status bit is set to a one.

Value on reset: 0

Variants

SE0 = 0

0: Not Low-speed device, perform EHCI reset.

J_STATE = 2

2: Not Low-speed device, perform EHCI reset.

K_STATE = 1

1: Low-speed device, release ownership of port.

UNDEFINED = 3

3: Not Low-speed device, perform EHCI reset.

Trait Implementations

impl Clone for LINE_STATUS_A

fn clone(&self) -> LINE_STATUS_A

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LINE_STATUS_A

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

Formats the value using the given formatter.

impl From<LINE_STATUS_A> for u8

fn from(variant: LINE_STATUS_A) -> Self

Converts to this type from the input type.

impl PartialEq for LINE_STATUS_A

fn eq(&self, other: &LINE_STATUS_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.
