[−][src]Enum olympia_core::registers::Flag

pub enum Flag {
    Zero,
    AddSubtract,
    HalfCarry,
    Carry,
}

Represents a CPU flag set after some instructions.

Note that many instructions leave flags alone, and others may repurpose them for side channel information.

Variants

Zero

The last arithmetic operation resulted in 0

AddSubtract

The last arithmetic operation was a subtract type operation 0 = Add, 1 = Sub

HalfCarry

The last arithmetic operation contained a carry between nibbles

Carry

The last arithmetic operation overflowed or underflowed

Methods

pub fn bit(&self) -> u8[src]
