pub struct NMOS { /* private fields */ }
Expand description
The struct implements a Flavour that emulates the Zilog Z80 NMOS version.

const CONSTANT_OUT_DATA: u8 = 0u8
The value being actually put on the data bus while executing the undocumented instruction
OUT (C),(HL)
.source§const ACCEPTING_INT_RESETS_IFF2_EARLY: bool = true
const ACCEPTING_INT_RESETS_IFF2_EARLY: bool = true
Should be
true
if the IFF2 is being reset early when accepting an interrupt, while an instruction
is being executed, so LD A,I
or LD A,R
may report modified IFF2 value.source§fn memptr_mix(msb: u8, lsb: u8) -> (u8, u8)
fn memptr_mix(msb: u8, lsb: u8) -> (u8, u8)
The way MEMPTR is being updated for:
LD (nnnn),A
, LD (BC),A
, LD (DE),A
and OUT (nn),A
is being controlled by this function. The current Accumulator value is being passed as msb
and
the lower 8-bits of the current destination address is being provided as lsb
.
The function should return the (MSB, LSB) value to set the MEMPTR with.source§fn begin_instruction(&mut self)
fn begin_instruction(&mut self)
This method is being called each time before an instructions is being executed or an interrupt is being
accepted, including NMI. It might modify some state and is being used together with Flavour::flags_modified
and Flavour::get_q to prepare a value applied to bits 3 and 5 of the Flags for the SCF/CCF instructions.
source§fn flags_modified(&mut self)
fn flags_modified(&mut self)
This method is being called each time an instructions modifies the Flags register.
source§fn get_q(&self, acc: u8, flags: CpuFlags) -> u8
fn get_q(&self, acc: u8, flags: CpuFlags) -> u8
Bits 3 and 5 of the returned value will be copied to the Flags register.

source§fn reset(&mut self)
fn reset(&mut self)
Should reset the state. Called by crate::Cpu::reset. The default implementation resets the state to default.
