Special Internal Relays
Special internal relays M8000 through M8077 are read/write internal relays used for controlling the CPU operation and
communication. Special internal relays M8080 through M8157 are read-only internal relays primarily used for indicating
the CPU statuses. All special internal relays cannot be used as destinations of advanced instructions.
Internal relays M300 through M315 are used to read input operand statuses of the IOREF (I/O refresh) instruction.
