Implementations

impl PIT

pub fn default() -> Self

pub fn init(&mut self)

initializes the PIT with current time of day

pub fn update(&mut self, mmu: &mut MMU)

pub fn set_mode_command(&mut self, val: u8)

port 0043: control word register for counters 0-2 called “8253/8254 PIT mode control word” in the interrupt list

Trait Implementations

impl Clone for PIT

fn clone(&self) -> PIT

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Component for PIT

fn in_u8(&mut self, port: u16) -> Option<u8>

returns Some if read was handled

fn out_u8(&mut self, port: u16, data: u8) -> bool

returns true if write was handled

fn int(&mut self, int: u8, cpu: &mut CPU, _mmu: &mut MMU) -> bool

returns true if interrupt was handled

fn out_u16(&mut self, _port: u16, _data: u16) -> bool

returns true if write was handled
