stack: Stack

Implementations

impl Cpu

pub fn new() -> Cpu

Returns a default instance of a Cpu

pub fn load<T>(&mut self, code: &[u8], addr: T) -> Result<(), CpuError>

where T: Into<Option<u16>>,

Loads code into the Cpu main memory at an optional offset. If no offset is provided, the Cpu will, by default, load the code into main memory at 0xC000

pub fn step_n(&mut self, n: u32) -> Result<u64, CpuError>

Runs N instructions of code through the Cpu

pub fn reset(&mut self)

pub fn step(&mut self) -> CpuStepResult

Runs a single instruction of code through the Cpu

pub fn nmi(&mut self)

Execute the Non-Maskable Interrupt handler. This ignores the interrupt flag and forces execution to the NMI

pub fn irq(&mut self)

Execute the Interrupt ReQuest handler if we currently are accepting maskable interrupts. Ignore it otherwise.
