Enum Channel 

#[repr(u8)]
pub enum Channel {
    MdecIn = 0,
    MdecOut = 1,
    Gpu = 2,
    Cd = 3,
    Spu = 4,
    Expansion = 5,
    OrderingTableClear = 6,
}

Channel index 0..=6 in the order the DMA controller presents them.

Variants

MdecIn = 0

RAM→MDEC: run-length coefficient data into the decoder. This is the direction the name refers to, not the direction of transfer to RAM – channel 0 feeds the MDEC, channel 1 drains it.

MdecOut = 1

MDEC→RAM: decoded macroblocks out of the decoder, 256 pixels (16x16) per macroblock at 15bpp.

Gpu = 2

RAM↔GPU.

Cd = 3

CD-ROM drive → RAM.

Spu = 4

SPU ↔ RAM.

Expansion = 5

Expansion port.

OrderingTableClear = 6

Ordering-table clear: writes a reverse-linked empty ordering table.

Implementations

impl Channel

pub const Cdrom: Channel = Channel::Cd

👎Deprecated:

renamed to Channel::Cd

Renamed to Channel::Cd.

impl Channel

pub const fn register_base(self) -> u32

Address of this channel’s register block.

pub const fn enable_bit(self) -> u32

Bit position of this channel’s enable flag in the global enable register.

Trait Implementations

impl Clone for Channel

fn clone(&self) -> Channel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Channel

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

Formats the value using the given formatter.

impl PartialEq for Channel

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

impl Copy for Channel

impl Eq for Channel
