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 STK14CA8, 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
