Struct BusSignals 

pub struct BusSignals {
    pub irq: bool,
    pub firq: bool,
    pub nmi: bool,
    pub halt: bool,
}

Interrupt and control signals returned by Bus::tick.

Each field corresponds to a physical input pin on the 6809 CPU. The default is all signals de-asserted (inactive).

Fields

irq: bool

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

firq: bool

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

nmi: bool

NMI request (edge-triggered — set true to trigger once).

halt: bool

Request the CPU to halt (e.g. watchdog expiry).

Trait Implementations

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 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.
