A Instruction (CPU)

Symbolic Syntax:

• @value
  • value is either:
    • a non-negative decimal constant
    • a symbol referring to such a constant Binary Syntax: 0value where value is a 15-bit binary number
• a 1 before the value would be a C Instruction (CPU) Semantics:
• Sets A register to value
• RAM[A] becomes selected register
  • ex) @21 sets the a register to 21, and RAM[21] becomes the selected RAM register
    • can now set RAM[A] by setting M=value
