Addressing ModesThis specification does not limit implementation of different addressing modes in the Heritage-1. However, it establishes the minimum to be provided. Those are the following:
Addressing Mode Example (pseudo assembler)
---------------------------------------------------------
Reg Immediate movi A, value
Reg Direct mov A, B
Mem Direct movd A, addr
Mem Indirect Indexed movx A, Y
Since peripherals are memory mapped, all memory addressing modes apply to peripherals as well.
