Question:

11. Expand the memory address space of the μP 3 computer from eight bits to nine bits.

Some registers will also need an additional bit. Use 512 locations of 16-bit memory.

Expand the address field by 1-bit by reducing the size of the opcode field by 1-bit. This will limit the number of different instructions to 128 but the maximum program size can now increase from 256 locations to 512 locations.
