The DSP Interface Register allows for the S-SMP to communicate with the S-DSP. This register is inside the S-DSP.[2] It is 16 bits wide, consisting of two 8-bit subregisters:

  • 00F2h holds the target DSPRAM address
  • 00F3h holds the data byte 00F2h points to

Its value is indeterminate upon reset.
