Function Documentation

_load_a_mem()

void _load_a_mem	(	struct z80 *	cpu,
		uint8_t *	memory
	)

loads user provided value from memory into register A

Parameters

cpu	z80 CPU object
memory	pointer to allocated block of memory

_load_idx_offset_n()

void _load_idx_offset_n	(	word *	index_register,
		uint8_t *	memory,
		word *	pc
	)

Parameters

index_register
memory
pc

_load_mem_a()

void _load_mem_a	(	struct z80 *	cpu,
		uint8_t *	memory
	)

loads the value of A into a user provided memory location

Parameters

cpu	z80 CPU object
memory	pointer to allocated block of memory

_load_mem_idx_offset_reg8()

void _load_mem_idx_offset_reg8	(	uint8_t *	reg,
		word *	index_register,
		uint8_t *	memory,
		word *	pc
	)

Loads a value into a memory location stored in an index register + an offset from a register.

Parameters

reg	register to load from
index_register	pointer to ix or iy index register
memory	block of memory containing the value to load
pc	pointer to program counter

_load_mem_reg16()

void _load_mem_reg16	(	word *	reg,
		uint8_t *	memory,
		word *	pc
	)

loads a 16-bit register pair with a user-provided value from memory

Parameters

reg	register pair to load
memory	pointer to allocated block of memory
pc	pointer to program counter register

Todo:

refactor PC to use z80 CPU object instead

_load_reg16_mem()

void _load_reg16_mem	(	word *	reg,
		uint8_t *	memory,
		word *	pc
	)

loads a user-provided value from memory into a 16-bit register pair

Parameters

reg	16-bit register pair
memory	pointer to allocated block of memory
pc	pointer to program counter

Todo:

refactor PC to use z80 CPU object instead

_load_reg16_nn()

void _load_reg16_nn	(	word *	reg,
		uint8_t *	memory,
		word *	pc
	)

Loads a user supplied value into a 16 bit register pair

Parameters

reg	register to load
memory	block of memory to retrieve nn from
pc	pointer to program counter

_load_reg8_mem_idx_offset()

void _load_reg8_mem_idx_offset	(	uint8_t *	reg,
		word *	index_register,
		uint8_t *	memory,
		word *	pc
	)

Loads a value into an 8-bit register from the memory location stored in an index register + an offset from memory.

Parameters

reg	register to load
index_register	pointer to ix or iy index register
memory	block of memory containing the value to load
pc	pointer to program counter
