Struct libnoentiendo::memory::mos652x::Cia

pub struct Cia { /* private fields */ }

The MOS 6526 Complex Interface Adapter (CIA). Contains two ports, two timers, a real-time clock, a shift register, and interrupt registers.

Implementations

impl Cia

pub fn new(port_a: Box<dyn Port>, port_b: Box<dyn Port>) -> Self

Trait Implementations

impl Memory for Cia

fn read(&mut self, address: u16) -> u8

Read a byte from this memory at the given address. Implementations may trigger side effects as a result of this read.

fn write(&mut self, address: u16, value: u8)

Write a byte to this memory at the given address.

fn reset(&mut self)

Reset this memory to its initial state, e.g. after a system reboot. Sometimes this will clear the contents of the memory, like with RAM. Other times this is a no-op, e.g. for ROM.

fn poll( &mut self, cycles_since_poll: u64, total_cycle_count: u64 ) -> ActiveInterrupt

Poll this memory to see if an interrupt has been triggered. Implementations may trigger an NMI or IRQ for any implementation-dependent reason.
