Notes:

  The 16-bit value is written in pairs.  The first 8-bits are the MSB and
  are destined for an even copper instruction address.  The second 8-bits are
  the LSB and are destined for an odd copper instruction address.
  After each write, the copper address is auto-incremented to the next memory position
  After a write to an odd address, the entire 16-bits is written to copper memory at once
