Notes

17.The six consecutive addresses must be in the order listed. W must be high during all six consecutive cycles to enable a nonvolatile cycle.

18.While there are 17 addresses on the STK17TA8, only the lower 16 are used to control software modes

19.I/O state depends on the state of G. The I/O table shown assumes G low
