Trait ZeroPage

pub trait ZeroPage {
    // Required methods
    fn is_zeropage(&self) -> bool;
    fn low(&self) -> u8;
    fn high(&self) -> u8;
}

Trait for instructions that can handle zeropage and regular addresses.

Zeropage are special address mode on the 6502 where less CPU-cycles and instruction size is used when accessing RAM below 0x0100.

Based on the is_zeropage the caller can decide if it only needs the low byte or both the low and high byte.

Required Methods

fn is_zeropage(&self) -> bool

Is the address a zeropage address

fn low(&self) -> u8

Get the lower byte of the address

fn high(&self) -> u8

Get the higher byte of the address
