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 15 addresses on the STK17T88, only the lower 13 are used to control software modes.
19. I/O state depends on the state of G. The I/O table shown assumes G low.
