Struct P2addr 

#[repr(transparent)]
pub struct P2addr(pub u32);

The Port Address register is used to set the mapped address in the LPC/eSPI memory space. For normal Ports, this is a 16-bit location in IO space or a 32-bit offset into PCIe address mapped space. It is not used for OOB, Bus Mastering, or Flash; see the PnOMFLEN register for those. For Endpoints, it is the base of a dword (64 bits). For Index/Data, it is the base of a word (32 bits). For mailbox memory, the address is modulus the length of the mailbox (x2 for both directions). So, if a 16-byte mailbox (single), the offset must have bits 3:0 set to 0 (that is &~0xF). If split directions, then normally bits 4:0 would be set to 0 (that is &~0x1F).

Implementations

impl P2addr

pub const fn off(&self) -> u16

Offset from 0 or the selected mapped base for matching memory or IO

pub const fn set_off(&mut self, val: u16)

Offset from 0 or the selected mapped base for matching memory or IO

pub const fn base_or_asz(&self) -> P2addrBaseOrAsz

The meaning is dependent on type of port:

pub const fn set_base_or_asz(&mut self, val: P2addrBaseOrAsz)

The meaning is dependent on type of port:

pub const fn idxoff(&self) -> u8

For index/register only: This is the byte offset of the Index relative to the data (before or after, based on IDX1ST)

pub const fn set_idxoff(&mut self, val: u8)

For index/register only: This is the byte offset of the Index relative to the data (before or after, based on IDX1ST)

pub const fn idx1st(&self) -> bool

For index/data register only: Is 1 if index is lower address than data (e

pub const fn set_idx1st(&mut self, val: bool)

For index/data register only: Is 1 if index is lower address than data (e

Trait Implementations

impl Clone for P2addr

fn clone(&self) -> P2addr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for P2addr

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

Formats the value using the given formatter.

impl Default for P2addr

fn default() -> P2addr

Returns the “default value” for a type.

impl PartialEq for P2addr

fn eq(&self, other: &P2addr) -> 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.
