Struct State 

pub struct State { /* private fields */ }

This struct stores the internal registers and flags of the 8080 CPU.

Implementations

impl State

pub fn flags(&self) -> u8

This method exposes the flag bits of the 8080 in the same format as the PSW pseudo-register, mz0a0p1c, where

• m is the sign flag;
• z is the zero flag;
• a is the auxilliary carry flag;
• p is the even-parity flag;
• c is the carry flag.

pub fn is_stopped(&self) -> bool

Whether or not the processor is in a stopped state (not executing operations from the PC). The processor will return to an active state if it receives an interrupt.

Note that if interrupts are disabled when the processor is halted, the processor will remain stopped until it is reset from outside.

pub fn is_interrupt_ready(&self) -> bool

Whether the processor is accepting interrupts; this is disabled automatically when an interrupt is received, to allow the interrupt to finish processing without being further disrupted. It is also set by the EI operation and reset by the DI operation.

impl State

pub fn new() -> Self

Creates a fresh state with the processor in an active state and all registers reset.
