Struct BusSignals 

pub struct BusSignals(/* private fields */);

Interrupt and control signals returned by Clocked::tick.

Each flag corresponds to a physical input pin on the 6809 CPU. Signals can be combined with | and tested with contains. The default is all signals de-asserted.

Example

use mc6809_core::BusSignals;

let signals = BusSignals::IRQ | BusSignals::NMI;
assert!(signals.contains(BusSignals::IRQ));
assert!(signals.contains(BusSignals::NMI));

Implementations

impl BusSignals

pub const NMI: Self

NMI pin state (level).

pub const FIRQ: Self

FIRQ line state (active = asserted, level-triggered).

pub const IRQ: Self

IRQ line state (active = asserted, level-triggered).

pub const RESET: Self

RESET pin asserted — the host loop should call Cpu::reset.

pub fn contains(self, other: Self) -> bool

Returns true if all bits in other are set in self.

pub fn is_empty(self) -> bool

Returns true if no signals are asserted.

pub fn insert(&mut self, signals: Self)

Assert one or more signals (set their bits).

pub fn remove(&mut self, signals: Self)

De-assert one or more signals (clear their bits).

Trait Implementations

impl BitAnd for BusSignals

type Output = BusSignals

The resulting type after applying the & operator.

fn bitand(self, rhs: Self) -> Self

Performs the & operation.

impl BitAndAssign for BusSignals

fn bitand_assign(&mut self, rhs: Self)

Performs the &= operation.

impl BitOr for BusSignals

type Output = BusSignals

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self

Performs the | operation.

impl BitOrAssign for BusSignals

fn bitor_assign(&mut self, rhs: Self)

Performs the |= operation.

impl BitXor for BusSignals

type Output = BusSignals

The resulting type after applying the ^ operator.

fn bitxor(self, rhs: Self) -> Self

Performs the ^ operation.

impl BitXorAssign for BusSignals

fn bitxor_assign(&mut self, rhs: Self)

Performs the ^= operation.

impl Clone for BusSignals

fn clone(&self) -> BusSignals

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BusSignals

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

Formats the value using the given formatter.

impl Default for BusSignals

fn default() -> BusSignals

Returns the “default value” for a type.

impl Not for BusSignals

type Output = BusSignals

The resulting type after applying the ! operator.

fn not(self) -> Self

Performs the unary ! operation.

impl PartialEq for BusSignals

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