Notes
18. The six consecutive addresses must be in the order listed. W must be high during all six consecutive cycles to enable a nonvolatile cycle.
19. While there are 15 addresses on the STK14D88, only the lower 14 are used to control software modes
20. I/O state depends on the state of G. The I/O table shown assumes G low.
