Crate yamos6502

Behavioral emulator of MOS 6502

Structs

• Mos6502
  Behavioral MOS 6502 emulator
• RegisterFile
  MOS 6502 register file

Enums

• AddressMode
• Insn
  Instruction representation. Nor particulary space-efficient (perhaps makes the code slower, too?), yet readable.
• MemoryError
  Memory errors
• Register
  Register
• RunError
  Run error
• RunExit
  Run normal exit
• StackWraparound
  Stack wraparound policy
• Status
  SR Flags (bit 7 to bit 0)

Constants

• IRQ_BRK_VECTOR
  When an interrupt is signaled (hardware or the software via BRK), the low and the high 8 bits of the program counter are loaded from a word at this address.
• MAX_MEMORY_SIZE
  No more than 64 KiB of memory is supported
• NMI_VECTOR
  When an non-maskable interrupt is signaled, the low and the high 8 bits of the program counter from a word at this address.
• RESET_VECTOR
  When a reset is requested, the low and the high 8 bits of the program counter are loaded from a word at this address.
• STACK_BOTTOM
  Bottom of the stack

Traits

• Memory
  A 16-bit addressable, 8-bit cell memory

Functions

• decode_insn
• encode_insn
• get_opcode_string
